Find out which one is bigger: 2 1 2 ÷ 3 5 or 2 1 3 × 1 2 7

Given expression: 2 1 2 ÷ 3 5 and 2 1 3 ÷ 1 2 7 Now, 2 1 2 ÷ 3 5 = 5 2 ÷ 3 5 = 5 2 × 5 3 = 25 6 = 4 1 6 Also, 2 1 3 × 1 2 7 = 7 3 × 9 7 = 9 3 = 3 Now, 4 > 3 . So, 2 1 2 ÷ 3 5 > 2 1 3 × 1 2 7 So, 2 1 2 ÷ 3 5 is bigger.

Find out which one is smaller: 1 4 of 9 1 5 or 3 1 5 ÷ 8 5

Given expressions: 1 4 of 9 1 5 and 3 1 5 ÷ 8 5 Now, 1 4 of 9 1 5 = 1 4 × 46 5 = 46 20 = 23 10 = 2 3 10 And, 3 1 5 ÷ 8 5 = 16 5 ÷ 8 5 = 16 5 × 5 8 = 16 8 = 2 Now, 2 < 2 3 10 So, 3 1 5 ÷ 8 5 < 1 4 of 9 1 5 . So, 3 1 5 ÷ 8 5 is smaller.

The capability of a can is 3 3 4 L . How many such cans are required to fill 90 L of oil?

Given, The capability of a one can is 3 3 4 L . We need to find the number of cans required to fill 90 L of oil. Let's divide the number of litter required to fill a can by the capacity of one can. = 90 3 3 4 = 90 15 4 = 90 15 × 4 1 = 6 × 4 = 24 cans Hence, this is the required answer.
