WebIf we had a simpler problem such as 3 + blank = 8, we would do 8-3 = 5. Similarly, for 2/5 + blank = 7/10, we would do 7/10 - 2/5. We can use 10 as a common denominator because 5 divides evenly into 10. Multiplying top and bottom of 2/5 each by 2 gives 4/10, so 2/5 = 4/10. So the blank is 7/10 - 2/5 = 7/10 - 4/10 = 3/10. The answer is 3/10. WebTo convert fractions into decimals, divide the denominator into 100, then multiply the answer by the numerator, and finally add the decimal point, i guess. For example, 3/5 is equal to 0.6 because 5 going into 100 is 20 which would make the decimal 0.2. The numerator is 3 and 0.2 x 3 = 0.6. I hope this helped! 2 comments ( 9 votes) Upvote
