Question

Proportional ratios : If I mow 75 % of 150 square meters of my grass, how much did I mow?​

Answer 1

You mowed 112.5 square meters of your grass.

Explanation:

First, convert the percentage to a fraction.

75% = 3/4

Then to find 75% of 150, multiply 3/4 and 150.

(3/4) * 150

(3*150)/4

450/4

112.5

We can now say that 75% of 150 is 112.5, meaning you mowed 112.5 square meters of your grass.

Answer 2

`\huge\boxed{\sf 112.5 \ m^2\\}`

Explanation:

Grass mowed:

= 75% of 150 m²

[Key: "of" means "to multiply" and "%" means "out of 100"]

`\displaystyle = (75)/(100 ) * 150\\\\= (75 * 15)/(10) \\\\= (1125)/(10) \\\\= 112.5 \ m^2\\\\\rule[225]{225}{2}`
