Question

Subtract 3/5 - 2/7?
1) 1/2
2) -1/2
3) 3/35
4) 11/35

Answer 1

First get a common denominator. Easiest way is to multiply the two denominators by each other 7x5=35

Then multiply the top and bottom of each fraction by the same number.

(3/5)x(7/7)= 21/35
(2/7)x(5/5)= 10/35

Now we can subtract the two fractions. The denominator stays the same.

(21/35) - (10/35) = 11/35

Answer 2

To subtract 3/5 - 2/7, find a common denominator, which is 35. Convert both fractions and subtract to get 11/35. Therefore, 3/5 - 2/7 equals 11/35.

Step-by-step explanation:

Subtracting Fractions

To subtract the fractions 3/5 and 2/7, we first need to find a common denominator. The lowest common denominator for 5 and 7 is 35. We convert each fraction so that they both have the denominator of 35:

• 3/5 becomes 21/35 (because 3 * 7 = 21)
• 2/7 becomes 10/35 (because 2 * 5 = 10)

Now we can subtract the two fractions:

21/35 - 10/35 = 11/35

Therefore, 3/5 subtracted by 2/7 equals 11/35.

So, the correct answer is option 4) 11/35.
