Natalie has 4 times as many biscuits as Anna. The total number of Natalie's and Anna's biscuits is 7 times of Elyse's. Natalie and Anna have 60 biscuits more than Elyse's. How many more biscuits does Natalie have than Anna?
| Natalie |
Anna |
Elyse |
| 4x7 |
1x7 |
|
| 7x5 |
1x5 |
| 28 u |
7 u |
5 u |
The total number of biscuits that Natalie and Anna have is repeated. Make the total number of biscuits that Natalie and Anna have the same. LCM of 5 and 7 is 35.
Total number of biscuits that Natalie and Anna have
= 28 u + 7 u
= 35 u
Number of more biscuits that Natalie and Anna have than Elyse
= 35 u - 5 u
= 30 u
30 u = 60
1 u = 60 ÷ 30 = 2
Number of more biscuits that Natalie has than Anna
= 28 u - 7 u
= 21 u
= 21 x 2
= 42
Answer(s): 42
