Zolol [24]

Answer:

$\frac{25}{8}$

Step-by-step explanation:

A fraction is a part of a whole .

A proper fraction is a fraction whose numerator is less than denominator .

For example $\frac{2}{3}\,,\,\frac{3}{4}$

An improper fraction is a fraction whose numerator is greater than denominator .

For example $\frac{5}{4}\,,\,\frac{8}{7}$

A mixed fraction is made up of whole number and a proper fraction .

Given : $4\frac{1}{6}\,,1\frac{1}{3}$

Solution :

$4\frac{1}{6}=\frac{4\times 6+1}{6}=\frac{25}{6}\\1\frac{1}{3}=\frac{3\times 1+1}{3}=\frac{4}{3}$

We need to divide $4\frac{1}{6}$ by $1\frac{1}{3}$ .

$4\frac{1}{6}\div 1\frac{1}{3}=\frac{25}{6}\div\frac{4}{3} \\\Rightarrow 4\frac{1}{6}\div 1\frac{1}{3}= \frac{25}{6}\times \frac{3}{4}=\frac{25}{8}$

At an ice cream store, a family ordered 1 banana split and 2 hot fudge sundaes, paying a total of $11 for their order. The next

Vladimir [108]

Answer:

$5 and $3

Step-by-step explanation:

Cost of banana split = b

Cost of hot fudge sundae = s

b + 2s = 11
4b + 3s = 29

<u>From the first equation we get: </u>

b = 11 - 2s

<u>Replacing in the second equation:</u>

4(11 - 2s) + 3s = 29
44 - 8s + 3s = 29
44 - 29 = 5s
15 = 5s
s = 15/5
s = 3

Then

b = 11 - 2*3 = 11 - 6 = 5

So banana split costs $5 and hot fudge sundae costs $3
