Final answer:
Leah made 6 snack bags with 3/4 pound of trail mix, and the equivalent expression for 2/3 divided by 4/5 is 5/6 after simplification.
Step-by-step explanation:
To find out how many snack bags Leah made, you can use the expression 3/4 ÷ 1/8. This expression shows the total amount of trail mix divided by the amount of trail mix in each bag. Dividing fractions requires multiplying the first fraction by the reciprocal of the second fraction. So this can also be written as 3/4 × 8/1 which equals × 3 bags.
The expression equivalent to 2/3 ÷ 4/5 is found by multiplying 2/3 by the reciprocal of 4/5, which is 5/4. The equivalent expression is 2/3 × 5/4, which simplifies to 10/12. This can be further simplified to 5/6, by dividing the numerator and the denominator by 2.
