Answer 1

Answer:

154 cm

Step-by-step explanation:

Let the height of smaller friend = x

The height of taller friend = 176cm

Ratio of height of smaller friend to the height of taller friend = 7:8

Height of smaller friend = x:176::7:8

= 176 × 7 ÷ 8 = x

= 1232 ÷ 8 = x

= 154 = x

x = 154cm

Therefore, height of the other friend is 154 cm.
