Answer: 7/8
Step-by-step explanation:
You can change all the fractions to have equivalent denominators.
The Least Common Denominator of 1 1/4 and 3/8 is 8. Now we can change the fractions.
1 1/4 = 1 2/8 = 10/8.
3/8 = 3/8.
Now we can subtract. Subtract the numerators of the first fraction from the numerators of the second fraction, and the denominators oft he first fraction to the denominators of the second fraction.
10/8 - 3/8 = 7/8.
Therefore, 1 1/4 - 3/8 = 7/8; the fourth answer.
The first number is 27 and the second number is 45 so the ratio would be 27;45
To multiply two fractions, we multiply the top number (numerators) together and the bottom numbers together (denominators) and then simplify.
8 x 5 = 40
15 x 6 = 90
40/90 can be simplified (÷10) to 4/9
