What is 7 divided by 2/3? (Need this done quickly)
Answers
Hi there! We make 7 a fraction, 7=7/1 and we change the division sign into a multiplication sign, we flip 2/3 into 3/2. Now, we have a multiplication problem of 7/1*3/2. 7*3=21 and 1*2=2, now we have a fraction of 21/2. 21/2 as a mixed number is 10 1/2. Therefore, the answer is 10 1/2
