2 answers:
5 1/4 times 1/2 = 2.625. as a fraction 2.625 is 2 5/8 because .625 could be drawn out to 625/1000 125 goes into 625 and 1,000 625 divided by 125 = 5 and 1,000 divided by 125 is 8 we already had 2 so 2 5/8 Hope I helped =)
Let
x-----> the number of hours that Candice spent doing her homework
y-----> the number of hours that Ronald spent doing his homework
we know that
convert mixed number to an improper fraction
so
-------> equation A
------> equation B
Substitute equation A in equation B
convert an improper fraction to a mixed number
therefore
<u>the answer is the option B</u>
