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.
7 5/16 + 3 3/4
place fractions over a common denominator and add.
Still don't understand
*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.
To find out how much Rita's baby brother weigh now, we need to add the weight he gained to his birth weight.
First, let's convert the mixed number 7 5/16 to an improper fraction.
To do so, we multiply the whole number (7) by the denominator (16) and add the numerator (5).
7 x 16 + 5 = 117
Now we place the sum (117) over the original denominator (16), which gives us the improper fraction 117/16.
Next, let's convert the mixed number 3 3/4 to an improper fraction.
3 x 4 + 3 = 15
15/4
To add these two fractions, we need a common denominator. In this case, the common denominator is 16 (the original denominator of 117/16).
To convert 15/4 to a fraction with a denominator of 16, we multiply both the numerator and denominator by 4.
15 x 4 = 60
4 x 4 = 16
So, 15/4 is equal to 60/16.
Now, we can add the two fractions together:
117/16 + 60/16 = 177/16
Therefore, Rita's baby brother currently weighs 177/16 pounds.
To express the decimal form of this fraction, we divide the numerator (177) by the denominator (16):
177 ÷ 16 = 11.0625
So, Rita's baby brother weighs approximately 11.0625 pounds.
