Write the following numbers 2, 3, 4 and 5 into the boxes to give the smallest possible answer.
? ?/7 x ? 1/?
Thank you in advance.
clearly, the whole number part must be as small as possible, so it'd be
2 ?/7 x 3 1/?
Now we want as large a denominator as possible, so I'd go with
2 4/7 x 3 1/5 = 8 8/35
Hmmm/ Nope,
3 4/7 x 2 1/5 = 7 6/7
