Your answer is 2,200 pupils.

If 990 is equal to 45% of the total amount of pupils, then to find 1% we can divide both 45 and 990 by 45.

990 ÷ 45 = 22, which is 1%, so then we multiply 22 by 100 to get 100% of the pupils, which gives us 2,200.

I hope this helps!

Which expression is equivalent to 0.7×0.23
Marina CMI [18]
The answer is D because when multiplied by 1/10 you move the decimal place of 7 one space to the left so 7 now equals .7 and when multiplied by 1/100 23 is moved two spaces to the left to make .23
