Answer:

so hcf of both the number is the largest measure he can use which is 15ml

Answer 2

Answer:

The largest measure he can use for both the recipes is 15 times.

Given:

A chef has two recipes. In recipe A he requires 105ml of oil and in recipe B he requires 135ml of oil.  

To find:

The largest measure he can use for both the recipe

Solution:

The amount of oil in recipe A = 105 ml

The amount of oil in recipe B = 135 ml

The largest measure can be found using HCF of 105 and 135

105 = 3 $\times$ 5 $\times$ 7

135 = 3 $\times$ 3 $\times$ 3 $\times$ 5

HCF = 3 $\times$ 5 = 15.

Then, the largest measure he can use for both the recipes is 15 times.
