Hey there!


6/7 = ?/21

= 6/7 = x/21

CROSS MULTIPLY the FRACTION

6(21) = x(7)

6(21) = 7(x)

126 = 7x

7x = 126

DIVIDE 7 to BOTH SIDES

7x/7 = 126/7

CANCEL out: 7/7 because it give you 1

KEEP: 126/7 because it help solve for the x-value

NEW EQUATION: x = 126/7

SIMPLIFY IT!

x = 18


Therefore, your answer is: 18


BECAUSE 18/21 is equivalent to 6/7 and they both give you approximately 86% (or simply 0.86) if you’re rounding your percentage/decimal form


Good luck on your assignment & enjoy your day!
