Debra received her £15 pocket money.
She spent:
1/3 on magazines
2/5 on a necklace
How much did she have left?
My answer
1/3 of 15 is 5
2/5 of 5 is 2
2 pound is left
Am I correct?
I disagree with your reasoning.
I read it that she spent 2/5 of her pocket money on a necklace
so she spent 6 on a necklace
So far she has spent 5 + 6 or 11
leaving her with £ 4
or
1/3 + 2/5 = 11/15 leaving 4/15
(4/15)(15) = 4
Thank you so much. I understand your method.
Thank you again:)
No, your calculation is not correct.
To find out how much Debra spent on magazines, you need to multiply £15 by 1/3:
£15 * (1/3) = £5
So she spent £5 on magazines.
To find out how much she spent on a necklace, you need to multiply £15 by 2/5:
£15 * (2/5) = £6
So she spent £6 on a necklace.
To calculate how much she had left, you need to subtract the total amount she spent (£5 + £6) from £15:
£15 - (£5 + £6) = £4
So Debra had £4 left after spending on magazines and a necklace.
Actually, your calculation is not correct. Let me guide you step by step on how to find the correct answer.
First, let's find out how much Debra spent on magazines. To calculate 1/3 of £15, we can divide £15 by 3.
£15 ÷ 3 = £5
So, Debra spent £5 on magazines.
Next, let's find out how much Debra spent on the necklace. To calculate 2/5 of £15, we can multiply £15 by 2 and then divide it by 5.
2/5 × £15 = (2 × £15) ÷ 5 = £30 ÷ 5 = £6
So, Debra spent £6 on the necklace.
To find out how much money Debra has left, we subtract the total amount she spent (£5 + £6 = £11) from her initial pocket money (£15).
£15 - £11 = £4
Therefore, Debra has £4 left.
