Question

Determine the longest tape which can be used to measure exactly the length 6m 58cm , 9m 40cm and 11m 28cm​

Answer 1

Step-by-step explanation:

find the hcf of all the 3 distance

You look to the example below and u can solve by urself so that u will get it

E.G

Find the hCF ( highest common factor )

7 m = 700 cm = 7 ∙ 5² ∙ 2² cm

3 m 85 cm = 385 cm = 11 ∙ 7 ∙ 5 cm

12 m 95 cm = 1295 cm = 37 ∙ 7 ∙ 5 cm

7 and 5 (common to all)

highest common factor = 7 ∙ 5 = 35

The longest tape = 35 cm

7 m = 20 ∙ 35 cm = 20 lengths

3 m 85 cm = 11 ∙ 35 cm = 11 lengths

12 m 95 cm = 37 ∙ 35 cm = 37 lengths

hope u will solve
