31/2 × 4 2/3 equal need for the break down

Turn them into mixed fractions first:
3 1/2 = 7/2 and 4 2/3 = 14/3

Then multiply the fractions:
7/2 x 14/3
Make sure you multiply the denominators together and multiply the numerators together, straight across.
7/2 x 14/3 = 98/6

Now simplify!
98/6 = 16 2/6 = 16 1/3

That’s your answer, 16 1/3

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
