Rita's baby brother weighed 7 5/16 pounds when he was born. Since then, her brother has gained 3 3/4 pounds. How much does Rita's baby brother weigh now? Express your answer as a fraction and as a decimal.

Answer 1

7 5/16 + 3 3/4

place fractions over a common denominator and add.

Answer 2

Still don't understand

Answer 3

*sigh*

7 5/16 + 3 3/4
= 7 5/16 + 3 12/16
= 7+3 + 5/16+12/16
= 10 17/16
= 11 1/16

clearly you need to review operations with fractions.
