Question

If ratio of 90 cm to 1.5 m is equal to 3: x find x

Answer 1

Step-by-step explanation:

90/150=3/x

3/5=3/x

1/5=1/x

x=5

Answer 2

we know

$1m=100cm$

$1.5m=150cm$

Given: $\frac{90}{150} =\frac{3}{x}$

cross multiply

$90x=3\times 150$

$x=\frac{3\times 150}{90}$

$x=5$

Hence $x=5.$
