Find the value of 3 17 ÷ - 4 85

Given that find the value of 3 17 ÷ - 4 85 3 17 ÷ - 4 85 = 3 17 × 85 - 4 = 3 17 × - 85 4 = - 3 17 × 85 4 = - 3 1 × 5 4 = - 15 4 = - 3 3 4 Hence, the required answer is - 3 3 4 .

Find the value of 2 19 ÷ 4 7

Given that find the value of 2 19 ÷ 4 7 To divide one rational number by the other non-zero rational number, we multiply the rational number by the reciprocal of the other. 2 19 ÷ 4 7 = 2 19 × 7 4 = 1 19 × 7 2 = 7 38 Hence, the required answer is 7 38 .

Find the value of 7 18 ÷ 28 17

Given that find the value of 7 18 ÷ 28 17 To divide one rational number by the other non-zero rational number, we multiply the rational number by the reciprocal of the other. 7 18 ÷ 28 17 = 7 18 × 17 28 = 1 18 × 17 4 = 17 72 Hence, the required answer is 17 72 .

Find the value of 3 5 ÷ 3

Given that find the value of 3 5 ÷ 3 To divide one rational number by the other non-zero rational number, we multiply the rational number by the reciprocal of the other. 3 5 ÷ 3 = 3 5 × 1 3 = 1 5 × 1 1 = 1 5 Hence, the required answer is 1 5 .

From a ribbon of length 7 1 2 m , Shreya used 4 1 4 m of ribbon. How much ribbon is left?

Total length of the ribbon = 7 1 2 m , Length of the ribbon Shreya used = 4 1 4 m Length of the ribbon left = Total length of the ribbon - Length of the ribbon Shreya used = 7 1 2 m - 4 1 4 m = 15 2 - 17 4 m = 30 4 - 17 4 m = 30 - 17 4 m = 13 4 m = 3 1 4 m Hence, 3 1 4 m length of the ribbon is left.

Rohan bought 9 m of cloth to stitch shirts. If one shirt requires 2 1 4 m of cloth, how many shirts can be stitched from the cloth Rohan has?

Length of the cloth Rohan bought = 9 m Length of the cloth required for one shirt = 2 1 4 m = 9 4 m Total number of shirts that can be stitched from the cloth = Length of the cloth Rohan bought ÷ Length of the cloth required for one shirt = 9 m ÷ 9 4 m = 9 × 4 9 m m = 4 Hence, 4 shirts can be stitched from the cloth Rohan.
