319 girls

Step-by-step explanation:

Given

Ratio of boys : girls = 15 : 11
No. of boys = 435

Let g be the number of girls
15/11 = 435/g
g = 435 x 11 / 15
g = 29 x 11
g = 319 girls

I have a 3 foot board that needs to be equally decided into 1/2 how many extra peices will I have

anygoal [31]

Answer:

No extra pieces.

Step-by-step explanation:

Given:

Total number of foot board = 3

Equally divided into = 1/2

Question asked:

How many extra pieces will I have = ?

Solution:

By dividing 3 by 1/2 we can find the extra pieces.

= $3\div\frac{1}{2}$

= $3\times\frac{2}{1}$

= $6$

Since, the remainder is zero, thus there is no any extra pieces I have.
