Fractions are equivalent to 9/8

9/8, 18/16, 27/24, 36/32, 45/40, 54/48, 63/56, 72/64, 81/72, 90/80, and so on ...

Explanation:

Two fractions are equivalent when they are both equal when written in lowest terms. The fraction 18/16 is equal to 9/8 when reduced to lowest terms. To find equivalent fractions, you just need to multiply the numerator and denominator of that reduced fraction (9/8) by the same integer number, ie, multiply by 2, 3, 4, 5, 6 ...

18/16 is equivalent to 9/8 once 9 x 2 = 18 and 8 x 2 = 16

27/24 is equivalent to 9/8 once 9 x 3 = 27 and 8 x 3 = 24

36/32 is equivalent to 9/8 once 9 x 4 = 36 and 8 x 4 = 32

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
