If Jack is paid £1800a month and he spends half of it on rent and the rest on food Bill's and savings in the ratio 4:3:2 how much does he spend on Bill's

Answer:
Jack spent 270 on bills
Step-by-step explanation:
First, divide 1800 to find the value of rent.
1800 ÷ 2 = 900
This means that 900 is split in the ratio 4:3:2. Add 4 to 3 and 2 and divide by 900.
4 + 3 + 2=9
900 ÷ 9 = 100
The ratio is food : bills : savings so just replace that to the ration and multiply.
food : bills : savings
4 : 3 : 2
900 x 3 = 270
