63 × 2/7 = 18
They are: 3/7 and 2/9 are the equivalent 27/63 and 14/63
lcm(7, 9) = 63 → equivalent fractions are: 3/7 = (3×9)/(7×9) = 27/63 2/9 = (2×7)/(9×7) = 14/63
h/9=7 multiply both sides by 9 h=63
2/7 * 5/9 = (2*5)/(7*9) = 10/63
3/7=x/63 189=7x 27=x
63 × 2/7 = 18
18 over 63 is 2/7
18/63 = 2/7
(63/7) / (22/14) = (63/11) meaning that it equals 63 over 11
They are: 3/7 and 2/9 are the equivalent 27/63 and 14/63
lcm(7, 9) = 63 → equivalent fractions are: 3/7 = (3×9)/(7×9) = 27/63 2/9 = (2×7)/(9×7) = 14/63
14 over 63 in simplest form is 2 over 9 because . first you have to see which one goes in both equallly . So its 7 divide in to both 7 / 14 is 2 and 63 / 7 is 9 So its 2 / 9 !
2/7 + 1/9 18/63 + 7/63 = 25/63 Then you can simplify if you are asked to. 63 is the Lowest Common Factor (LCM), you need to convert the fraction to the LCM before you can add the fractions.
h/9=7 multiply both sides by 9 h=63
2/7 * 5/9 = (2*5)/(7*9) = 10/63
63 / 84 = (3*3*7) / (2*2*3*7) cancelling out 3*7 leaves 3 / (2*2) = 3/4
