Answers ID : in-4-conversion-of-units [3] (1) 20235 Let us first convert all the individual given units into meters. We know that 1km = 1000m. Therefore 17km = 17 1000 = 17000m. There are 100m in 1hm. Therefore, in 28hm there will be 28 100 = 2800m. There are 10m in 1dam. Therefore, in 40dam there will be 40 10 = 400m. Step 4 Hence, 17km 28hm 40dam 35m = 17000m + 2800m + 400m + 35m = 20235m. (2) 1.8 We know, 1 decigram = 0.1 grams. Therefore, 18 decigrams = 0.1 18 = 1.8 grams (3) 1.9 We know, 1 liter = 0.1 decaliters. Therefore, 19 liters = 0.1 19 = 1.9 decaliters. (4) Rs. 792 We are given that the cost of 1 kg of bananas is Rs. 66 and we have to find the cost of 12 kg bananas. Cost of 12 kg bananas = 12 Cost of 1 kg bananas = 12 Rs. 66 = Rs. 792 Therefore, the cost of 12 kg bananas is Rs. 792.

(5) 99000 litres ID : in-4-conversion-of-units [4] Length of the cuboid, L = 11 m Width of the cuboid, W = 3 m Height of the cuboid, H = 3 m Capacity of the tank = L W H = 11 3 3 m 3 = 99 m 3 Since, 1 m 3 = 1000 litres Now, the capacity of the tank = 99 1000 litres = 99000 litres Therefore, the volume of the water that tank can hold is 99000 litres. (6) 12009 We know that there are 1000m in 1km. Since, 1km = 1000m, 12km will be equal to 12 1000m, or 12000m. Hence, 12km 9m = 12000m + 9m = 12009m.

(7) 708 km ID : in-4-conversion-of-units [5] Distance already traveled by the Sunil = 492 kms Journey remaining = 59 % Journey traveled so far = 100-59 = 41 % Therefore, 41% of total distance equals 492 kms Step 4 492 100 100% of distance equals = 41 = 1200 km = Total Distance Step 5 therefore, the remaining distance to be traveled by Sunil = Total distance - distance already traveled = 1200-492 km = 708 km Step 6 Therefore, 708 km is still have to traveled by Sunil. (8) 31000 Since 1l = 1000ml, we can say that 31l = 31 1000 = 31000ml.

(9) 510094.312 l ID : in-4-conversion-of-units [6] Total water in a small dam = 1014 kl 98 l 485 ml 1014 kl into l = 1014 1000 = 1014000 l 485 ml into l = 485/1000 = 0.485 l Total water in the dam in l = 1014000 l + 98 l + 0.485 l = 1014098.485 l Water let out from the dam = 504 kl 4 l 173 ml 504 kl into l = 504 1000 = 504000 l 173 173 ml into l = = 0.173 l 1000 Water let out from the dam in l = 504000 l + 4 l + 0.173 l = 504004.173 l Water left in the dam = Total water in the dam in l Water let out from the dam in l = 1014098.485 504004.173 = 510094.312 l Step 4 Therefore, 510094.312 l water is remaining in the dam. (10) 41000 We know that there are 1000 meters in 1 kilometer. Therefore, in 41 kilometers we will have 41 1000 = 41000 meters.

(11) 990.48 ID : in-4-conversion-of-units [7] Let us first convert every given unit to liters individually. We know that 1 hl = 100l, which means 3hl = 300l 1 dal = 10l, which means 69dal = 690l 1 cl = 0.01l, which means 48cl = 0.48l Now let us add the converted units together: 300l + 690l + 0.48l = 990.48l Step 4 Thus, 3hl 69dal 48cl = 990.48l (12) 208 We know that there are 10dm in 1m. Therefore, in 12m there will be 12 10 = 120dm. Hence, 12m 88dm = 120dm + 88dm = 208dm. (13) 16015 As we know that 1kl = 1000l, we can say that 16kl will be equal to 16000l. From step 1 it is clear that the above quantity 16kl 15l can also be written as 16000l + 15l = 16015l (14) A) 430 We know that there are 10 millimeters in 1 centimeter. Therefore, in 43 centimeters there will be 43 10 = 430 millimeters.

ID : in-4-conversion-of-units [8] B) 490 We know that there are 10 millimeters in 1 centimeter. Therefore, in 49 centimeters there will be 49 10 = 490 millimeters. C) 100 We know that there are 10 millimeters in 1 centimeter. Therefore, in 10 centimeters there will be 10 10 = 100 millimeters. D) 230 We know that there are 10 millimeters in 1 centimeter. Therefore, in 23 centimeters there will be 23 10 = 230 millimeters. (15) A) 110 We know, 1 meter = 10 decimeters. Therefore, 11 meters = 10 11 = 110 decimeters. B) 20000 We know, 1 liter = 1000 milliliters. Therefore, 20 liters = 1000 20 = 20000 milliliters.

ID : in-4-conversion-of-units [9] C) 600 We know, 1 liter = 100 centiliters. Therefore, 6 liters = 100 6 = 600 centiliters. D) 190 We know, 1 meter = 10 decimeters. Therefore, 19 meters = 10 19 = 190 decimeters.
