What is 56.25% as a fraction
Nastasia [14]
<span>Example: 56.25%/100 = .5625, Next, count the number of digits to the right of the decimal point, say that number is n, and multiply and divide the decimal by 10^n. For your example n = 4 so multiply and divide the decimal by 10^4, which is 10000, giving 5625/10000 which is the fraction sought. This last operation converts the decimal fraction to a whole number needed for the numerator of the fraction. </span>

You are helping to plan an awards banquet for your school, and you need to rent tables to seat 180 people. Tables come in two si
pshichka [43]

Answer:

An equation modeling the situation  is : 4 m + 6 n  = 180

Step-by-step explanation:

Here,  the total number of guests in the banquet hall = 180

Let us assume number of tables ordered  with capacity of

4 people each  = m

And number of tables ordered  with capacity of 6 people each  = n

So, total number of people in m tables = m x ( Capacity of 1 table)

=  m x (4)  = 4 m

And, total number of people in n tables = n x ( Capacity of 1 table)

=  n x (6)  = 6 n

So, the total capacity of ( m + n) tables  = 4 m + 6 n

Also, the total required capacity  = 180

⇒  4 m + 6 n  = 180

Hence, an equation modeling the situation  is : 4 m + 6 n  = 180
