Convert 3 meters to cm:
3 meters = 300 cm.

$$text{Ratio} = frac{60}{300} = 1:5$$60/300​=1:5

Explanation

Given that 40% of a number is equal to two-third of another number, we need to find the ratio of the first number to the second number.

Let's assume that the first number is x and the second number is y. 40% of x is equal to 2/3 of y.

We can write this as: 0.4x = 2/3 y To find the ratio of x to y, we can divide both sides by y: 0.4x/y = 2/3

Simplifying further, we get: x/y = (2/3)/(0.4) x/y = 5/3

Therefore, the ratio of the first number to the second number is 5:3.

Explanation

The ratio of boys to girls is given as 3:4, and the total number of students in the class is 28.

Step 1: Add the parts of the ratio

Step 2: Calculate the value of one part

Each part of the ratio represents:

Step 3: Find the number of boys

The boys' share is 3 parts, so:

Explanation

The given ratio 3:5 can be simplified by multiplying both numbers by 10, which results in:

3 × 10 = 30

5 × 10 = 50

So, the ratio 3:5 is equal to the fraction 30:50.
