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!
11.) 4/5 * 3/4 = 12/20 reduces to 3/5
12.) 5 / (1/3) = 5 * 3 = 15
13.) 5 3/6 * 1 1/11 = 33/6 * 12/11 = 396/66 = 6
14.) 3 5/9 * 3/8 = 32/9 * 3/8 = 96/72 reduces to 4/3 or 1 1/3
15.) (2 5/6) / (1 1/2) = (17/6) / (3/2) = 17/6 * 2/3 = 34/18 reduces to 17/9 or
1 8/9.
16.) 24 / (2 3/4) = 24/(11/4) = 24 * 4/11 = 96/11 = 8 8/11
17.) 7 1/2 * 5 4/5...estimate : 8 * 6 = 48
18.) 9 8/15 * 11...estimate : 10 * 11 = 110
19.) (48 5/9) / (7 1/8)...estimate : 49/7 = 7
20.) (50 3/7) / (9 2/3)...estimate : 50/10 = 5
