420g of flour is to be divided in a ratio of 7:3 for two different recipes, find the smaller amount.

126 g

Step-by-step explanation:

Sum the parts of the ratio, 7 + 3 = 10 parts

Divide the quantity of flour by 10 to find the value of one part of the ratio

420g ÷ 10 = 42g ← value of 1 part of the ratio, thus

3 parts = 3 × 42g = 126g ← smaller amount

∞ this is your sign
