Which of the following numbers is proportional to 84/108?
lara [203]

Proportional numbers are numbers with the same equivalent ratio

98/126 is proportional to 84/108

The number is given as:

Number = \frac{84}{108}

Reduce fraction to the lowest term

Number = \frac{7}{9}

Reduce 86/110 to the lowest term

Number = \frac{86}{110}

Divide by 2/2

Number = \frac{43}{55}

43/55 is not equivalent to 7/9

Reduce 98/126 to the lowest term

Number = \frac{98}{126}

Divide by 14/14

Number = \frac{7}{9}

7/9 is equivalent to 7/9.

Hence, 98/126 is proportional to 84/108
