Well, the unit rate in the table is approximately 1.143 (8/7)
So, the only lines which have unit rate in between 1.143 and 2 are Line 3 (1.5) and Line 4 (1.2).
I am pretty sure your answer will be 96783564.8, but it may need to be rounded. If I am wrong, I am sorry.
Hope this helps~!
The answer is 3, if it is in square meters it must be a square therefore each side is the same length
A = Andrew
S = Sister
A : S
2 : 3
2 + 3 = 5
250 ÷ 5 = 50
2 × 50 = 100
3 × 50 = 150
∴ A : S
100 : 150
So Andrew keeps £100 of his salary every week.
Of this, he saves 12%:
100 × (12 ÷ 100) = 12
So he saves £12 every week
360 ÷ 12 = 30
∴ it will take him 30 weeks to save £360.
