Maria is setting aside 2/7 of her salary to buy gifts for her husband and 1/4 for grocery shopping. What is the fraction of the salary that María will use for these expenses?

Answer 1

To find the fraction of Maria's salary that she will use for these expenses, we need to add the fractions for buying gifts and grocery shopping.

2/7 + 1/4

To add these fractions, we need to find a common denominator, which in this case is 28.

2/7 is equivalent to 8/28 because 2 x 4 = 8 and 7 x 4 = 28.

1/4 is equivalent to 7/28 because 1 x 7 = 7 and 4 x 7 = 28.

So, 2/7 + 1/4 = 8/28 + 7/28 = 15/28.

Therefore, the fraction of Maria's salary that she will use for buying gifts and grocery shopping is 15/28. Answer: \boxed{\dfrac{15}{28}}
