Helen, Ivy and Jane inherit some money in the ratio 2 : 3 : 5. Ivy gets £1500. How much was there altogether?

£5000

Step-by-step explanation:

→ Divide the price by Ivy's ratio

1500 ÷ 3 = 500

→ Multiply 500 by each ratio and add the total

( 2 × 500 ) + ( 3 × 500 ) + ( 5 × 500 ) = 5000

5000

Step-by-step explanation:

Helen = 2

Ivy = 3

Jane = 5

Total ratio is 10

Ivy got 1500 so:

3/10 × ? = 1500

If we solve this above equation the answer is 5000

let's prove:

Ivy 3/10 × 5000 = 1500

Hence, total is 5000

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
