Answer: 5 1/4=21/4
Step-by-step explanation:
3 3/4 +1 1/2
Need to find the common denominator for 1 1/2
Multiply by 2 for denominator and numerator for 1 1/2
=3 3/4+ 1 2/4
=4 6/4
= 5 2/4
= 5 1/5
Even though there is no multiple choice. I still know the answer.
For this case we must find an expression equivalent to:
[tex]3 \frac {3} {4} +1 \frac {1} {2}[/tex]
We have to:
[tex]3 \frac {3} {4} = \frac {4 * 3 + 3} {4} = \frac {15} {4}\\1 \frac {1} {2} = \frac {2 * 1 + 1} {2} = \frac {3} {2}[/tex]
Rewriting the expression:
[tex]\frac {15} {4} + \frac {3} {2} = \frac {2 * 15 + 4 * 3} {8} = \frac {30 + 12} {8} = \frac {42} { 8} = \frac {21} {4}[/tex]
If we convert to a mixed number we have:
[tex]5 \frac {1} {4}[/tex]
ANswer:
[tex]5 \frac {1} {4} = \frac {21} {4}[/tex]
