Step-by-step explanation:
so x% of 40 is 15
the equation for that is
x/100 * 40 = 15
40x/100 = 15
multiply 100 on both sides
40x = 1500
divide 40 on both sides
37.5
37.5% of 40 is 15

Answer:
Step-by-step explanation:
To change a decimal into a percent you multiply by 100.
If there is a fraction that you need to convert into a percent. Completely divide the fraction. 4/5 = 0.8 then multiply by 100 you get 80%. This means that 4 is 80% of 5
Answer:
38cm is the circumference
Explanation:
circumference = diameter x 3.14
diameter = 12
circumference = 3.14 x 12 = 37.68
Now we need to round to the nearest whole
36 and 38 are the nearest wholes to 37.68. We need to minus and then find smallest difference between the numbers; meaning the smaller the difference the closer it is.
37.68 - 36 = 0.68
38 - 37.68 = 0.32
37.68 is more closer so we can round this to 38.
