Multiply fractions and decimals practice
Sure! Here are some practice problems for multiplying fractions and decimals:
1) Multiply 3/4 by 2/5.
- Solution: (3/4) * (2/5) = 6/20 = 3/10
2) Multiply 1/3 by 0.25.
- Solution: (1/3) * 0.25 = 0.08333... = 1/12
3) Multiply 4/5 by 0.6.
- Solution: (4/5) * 0.6 = 2.4/5 = 24/50 = 12/25
4) Multiply 2/3 by 0.8.
- Solution: (2/3) * 0.8 = 1.6/3 = 16/30 = 8/15
5) Multiply 7/8 by 0.125.
- Solution: (7/8) * 0.125 = 0.875/8 = 7/64
Remember to simplify the fractions if possible. Practice these problems to gain confidence in multiplying fractions and decimals!
Sure! Here's a step-by-step guide on how to multiply fractions and decimals:
1. Multiplying Fractions:
a. Multiply the numerators (the top numbers) together.
b. Multiply the denominators (the bottom numbers) together.
c. Write the product of the numerators over the product of the denominators.
d. Simplify the fraction, if possible.
Example:
Multiply 3/4 by 2/5.
Solution:
a. 3 x 2 = 6
b. 4 x 5 = 20
c. The product is 6/20.
d. Simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 2. The simplified fraction is 3/10.
2. Multiplying Decimals:
a. Multiply the two decimals as if they were whole numbers.
b. Count the total number of decimal places in both factors.
c. Place the decimal point in the product so that it has the same number of decimal places as the total counted in step 2b.
Example:
Multiply 0.75 by 2.5.
Solution:
a. 75 x 25 = 1875
b. There are a total of 2 decimal places in the two factors.
c. Place the decimal point in the product so that it has 2 decimal places, which gives us 18.75.
