What is the answer to 3/4 divided by 2/5
The Correct Answer and Explanation is :
To solve the problem of dividing ( \frac{3}{4} ) by ( \frac{2}{5} ), you can follow these steps:
Step 1: Understand Division of Fractions
Dividing fractions is not as straightforward as dividing whole numbers. Instead of dividing directly, we can use the rule that states:
[
\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}
]
In this case, you will multiply by the reciprocal of the second fraction.
Step 2: Find the Reciprocal
The reciprocal of ( \frac{2}{5} ) is ( \frac{5}{2} ). This means you will rewrite the division problem as a multiplication problem:
[
\frac{3}{4} \div \frac{2}{5} = \frac{3}{4} \times \frac{5}{2}
]
Step 3: Multiply the Fractions
Now you can multiply the fractions together. To multiply fractions, you simply multiply the numerators together and the denominators together:
[
\frac{3 \times 5}{4 \times 2} = \frac{15}{8}
]
Step 4: Simplify if Necessary
In this case, ( \frac{15}{8} ) is already in its simplest form. However, you can also express it as a mixed number. To convert ( \frac{15}{8} ) into a mixed number, divide the numerator by the denominator:
- ( 15 \div 8 = 1 ) with a remainder of ( 7 ).
Thus,
[
\frac{15}{8} = 1 \frac{7}{8}
]
Final Answer
The result of ( \frac{3}{4} \div \frac{2}{5} ) is ( \frac{15}{8} ) or ( 1 \frac{7}{8} ).
Conclusion
Understanding how to divide fractions by using the reciprocal can make the process straightforward. Always remember to simplify your final answer where possible, and converting to a mixed number can provide a clearer understanding of the quantity represented by the fraction.
