Answer 1

Given :-

• The length of a piece of cloth is 40 m.If it is cut into three pieces in the ratio 4:7:9

To find :-

• Length of three pieces

Solution :-

★Let the length of pieces be 4x , 7x and 9x

According to the question

→ 4x + 7x + 9x = 40

→ 20x = 40

→ x = 40/20

→ x = 2

Hence,

• Length of pieces
• 4x = 4 × 2 = 8m
• 7x = 7 × 2 = 14m
• 9x = 9 × 2 = 18m

Answer 2

Step-by-step explanation:

☞let the lengths cut be 4x,7x,7x respectively

☞given,4x+7x+9x=40m

☞ 20x=40m

☞or,x=40/20=2m

☞so the length of the three pieces are

☞4x=4×2 = 8m

☞7x=7×2 = 14m

☞9x=9×2 = 18m
