2 equivalent fractions for 15 and 23 = 30/46, 45/69
two fractions are equivalent 21 over 23 = 42/46, 63/69
Assuming you mean (5/31)/(15/23) the answer is 115/466 if my math is right. With divisions of fractions you can set it up as a multiplication, but you invert the second fraction. Here is an example: 5/31 divided by 15/23 is the same as 5/31 x 23/15 due to the properties of fractions. so 5 x 23 = 115 and 31 x 15 = 466, so the answer is 115/466. There may be a reduction, but I havent looked for any divisible factors.

It is usually easier to convert mixed numbers to improper fractions and then do the subtraction. To add/subtract fractions, the denominators (bottom numbers) must be equal; so first convert the fractions into equivalent fractions with the same denominator. Then the numerators (top numbers) are added/subtracted and the resulting fraction simplified (converting any improper fractions to mixed numbers); → 3 5/6 - 2 7/15 = (3×6+5)/6 - (2×15+7)/15 = 23/6 - 37/15 = (23×5)/(6×5) - (37×2)/(15×2) = 115/30 - 74/30 = (115 - 74)/30 = 41/30 = (1×30 + 11)/30 = 1 11/30
15/23=30/46
First convert both fractions to the same denominator... 2/5 = 8/20 and 3/4 = 15/20. Now - simply add the top numbers together... 8+15 = 23, Therefore 23/20 = 1 & 3/20
420/115 = 84/23 84 = 23 + 23 + 23 + 15 3 and 15/23
