Pooja writes the ratio x/3=y/4

Question

to help her increase the size of a two-dimensional shape. If the new value of x
is 15 units, what will be the value of y
?(1 point)
units

Answer 1

To solve the equation \( \frac{x}{3} = \frac{y}{4} \) for \( y \) when \( x = 15 \), we can start by substituting \( x \) into the ratio:

\[ \frac{15}{3} = \frac{y}{4} \]

Now simplify the left side:

\[ 5 = \frac{y}{4} \]

Next, to solve for \( y \), we can multiply both sides by 4:

\[ y = 5 \times 4 \]

\[ y = 20 \]

Thus, the value of \( y \) is \( 20 \) units.
