Answer:
Manuel owes more to Calvin(75 cents) as compared to Lester(50 cents).
Explanation:
We are given the following information in the question:
Manuel borrowed 50 cents from Lester and 75 cents from Calvin. Manuel claims that he owes lee to Calvin.
Manuel's claim is wrong.
This could be understood by comparing:
![\displaystyle(-3)/(4)~and~\displaystyle(-1)/(2)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ienec4nzwc913r8aaqaht0jjgmhen84ic5.png)
The negative sign here states that this amount is owed to someone, we do not own this money.
![\displaystyle(-3)/(4)~and~\displaystyle(-1)/(2)\\\\\displaystyle(-3)/(4)~and~\displaystyle(-2)/(4)\\\\\displaystyle(-3)/(4) < \displaystyle(-2)/(4)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/myjeuvkngfeoutxkv5muqcz5lm45cbpunb.png)
![\displaystyle(3)/(4)* \text{1 dollar} = 75\text{ cents}\\\displaystyle(1)/(2)* \text{1 dollar} = 50\text{ cents}](https://img.qammunity.org/2020/formulas/mathematics/middle-school/4s5jazb5e98cpfhz36vcu2rvw7ho6z41ez.png)
Thus, Manuel owes more to Calvin(75 cents) as compared to Lester(50 cents).
