42.7 divided by 7

36.48 divided by 6

7.29 divided by 9

Answer:

90° counter clockwise rotation of point 0(x, y) about origin = (-y, x)

Step-by-step explanation:

Following are the rules for a counter clockwise rotation of 90 degrees about the origin for a point O(x,y):

1. Invert the sign of the value of y.

2. Switch x and y with each other.

For example, a point A(5,2) after rotation gives a point B(-2,5) using the rules given above. The points on the x-y plane are shown in the image attached.

Ratio is the relationship between the number of same unit to verify the how bigger or smaller is a number to the another when we compare two quantities to each we write them in the form of the ration. For the equivalent ratio we can multiply or subtract a value at both numerator and the denominator.The equivalent ratio of the given number is 10/15.

Given-

We have to find out the equivalent ratio of the given ratio, which is 2:3.To get the value of ratio we need to know about the term "ratio".

What is the ratio?

Ratio is the relationship between the number of same unit to verify the how bigger or smaller is a number to the another when we compare two quantities to each we write them in the form of the ratio.For the equivalent ratio we can multiply or subtract a value at both numerator and the denominator.

Now to find out the equivalent ratio we can multiply or divide both the numerator and the denominator of the given ratio. The given ratio,

Let r be the equivalent ratio of the given number. Multiply the given ratio with number 5 in both numerator and denominator.

Hence the equivalent ratio of the given number is 10/15.
