Explain how to calculate a number that is equal to 2.1/1.5.

1.4

Step-by-step explanation:

Given the expression 2.1/1.5.

This can also be expresses as;

2.1/1.5

= 21/10 ÷ 15/10

= 21/10 × 10/15

= 21/15

= 7/5

= 1.4

Hence the result is 1.4

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
