Answer:
When multiplying fractions, multiply the top number by the top number, and the bottom number by the bottom number.
So we have: (9x2)/(10x5).
This simplifies to: 18/50, or 9/25.

Let, the cost of a belt = x
cost of a wallet = y
Then, system of equations would be:
x + y = 42
7x + 4y = 213
Multiply 1st equation by 4,
4x + 4y = 168
Substitute it from 2nd equation,
3x = 45
x = 15
Now, substitute it in 1st equation,
15 + y = 42
y = 42 - 15 = 27
In short, Belt costs $15 and wallet costs $27
Hope this helps!
