What does k equal in the proportion k/4=33/20

Mathematics
1 answer:
Firlakuza [10]3 years ago
3 0

Answer:

x =  \frac{33}{5}

or

x = 6 \frac{3}{5}

or

x = 6.6

Step by Step:

Step 1: Rewrite the equation (I used x instead of k.)

\frac{x}{4}  =  \frac{33}{20}

Step 2: Make x a loner by moving the 4 to the right side.

4 \times  \frac{x}{4}  =  \frac{33}{20}  \times 4

Step 3: Cancel multiplied terms on the left, multiply numbers on the right.

x =  \frac{165}{100}

Step 4: Simplify.

x =  \frac{33}{5}
