Question

Dorothy has green and blue beads in the ratio 1:4. She has 80 beads altogether. How many of each colour does she have?

Answer 1

Step-by-step explanation:

Let the no. of green beads be x.

than, no. of blue beads will be 4x.

We know, x + 4x = 80

5x = 80

x = 16

therefore, no. of green beads are 16, while the no. of blue beads is (16×4)= 64.

ANSWER VERIFICATION

total no. of beads= 16 + 64 = 80 {first condition is true}

16/64 = 1:4 {second condition is also true}

Thus, answer is correct.

But not recommended for students to verify solution everytime while solving!!!...
