Sam had 4/5 yards of yarn. He used 3/8 of the yarn. How many yards of yarn did he use in lowest terms.
"of" usually means multiplication
so, 3/8 of 4/5 = 3/8 * 4/5 = 12/40 = 3/10
Sorry to say Ms. Sue has passed away.
3/8 * 4/5 = ?
To find out how many yards of yarn Sam used in lowest terms, we need to subtract the amount used from the total amount.
To subtract fractions, we need to have a common denominator. In this case, the least common denominator (LCD) between 5 and 8 is 40.
Now, let's convert the fractions to have a denominator of 40:
4/5 = (4/5) * (8/8) = 32/40
3/8 = (3/8) * (5/5) = 15/40
Now we can subtract the two fractions:
32/40 - 15/40 = (32 - 15)/40 = 17/40
Therefore, Sam used 17/40 yards of yarn in lowest terms.
