For the third circle, in the first row, the answer is 4
For the third circle, in the second row, the answer is 20
For the third circle, in the third row, the answer is 20
For the circles in the first row:
For the first circle,
5 × 2 = 10 ; 10 ÷ 2 = 5
For the second circle,
3 × 4 = 12; 12 ÷ 2 = 6
∴ For the third circle,
2 × 4 = 8; 8 ÷ 2 = 4
∴The answer is 4
For the circles in the second row:
For the first circle,
4 × 5 = 20; 20 - 8 = 12
For the second circle,
6 × 5 = 30; 30 - 17 = 13
∴ For the third circle,
5 × 5 = 25; 25 - 5 = 20
∴ The answer is 20
For the circles in the third row:
For the first circle,
16 ÷ 4 = 4; 4 + 4 = 8
For the second circle,
24 ÷ 4 = 6; 6 + 6 = 12
∴ For the third circle,
40 ÷ 4 = 10; 10 + 10 = 20
∴ The answer is 20
Hence,
For the third circle, in the first row, the answer is 4
For the third circle, in the second row, the answer is 20
For the third circle, in the third row, the answer is 20
2. We have 25+15+10=50 minutes total work out, 25 lifting, so a ratio of
25:50 which is simplified to
Answer: 1:2
3.

This is because Andrea converted the Percentage wrong.
to Convert a Percent to a Decimal, she should have divided by 100
so 5 divided by 100 = 0.05 [not 0.5]
Andrea should have multiplied 300 by 0.05 instead to get the right answer
quickly finding 10% of a number means to simply move the decimal to the left one place
so 10% of 300 is 30
since 5% is half of 10%
half of 30 is 15
and so 5% of 300 is 15
You could four times because there are four letters in the word cube, so there are only four possible ways you could spell it.
Hope this helps:)

Well since 19/50 can't be simplified you have to double 9/25 which is 18/50 so then add 18 + 19 = 37 So 18/50 + 19/50 = 37/50 so 37/50 of the students ride the bus or walk to school.
