The formula for the problem is % over one hundred equals is over of. this means you would set it up like 25/100 is equal to (a variable in this case because you don’t know is) over 10. then you solve for the variable. remember that you’re trying to get the variable by itself. if you need not help call me 2562664950

ruben is buying bricks for a project. he knows that 5 bricks weigh 26 1/4. he wants to know the weight of 24 bricks

Answer:

the weight of 24 bricks is :

$124\frac{4}{5}$

Step-by-step explanation:

$26\frac{1}{4} =26+\frac{1}{4} =\frac{26\times 4}{4} +\frac{1}{4} =\frac{105}{4}$

It is clear that there is a proportional relationship between the number of bricks and their weights then :

$\frac{26\frac{1}{4} }{5} =\frac{x}{24} \Longrightarrow \frac{\left( \frac{105}{4} \right) }{5} =\frac{x}{24} \Longrightarrow \frac{26}{5} =\frac{x}{24}$
