Answer 1

Answer:

$6.25 or $6 and 25 cents

Step-by-step explanation:

Ms.Shanks collects $\ 1\dfrac{3}{4},\ \ \dfrac{3}{4},\ \ \dfrac{1}{4},\ \ 2\dfrac{2}{4}$,and $\ 1$ from five of her students.

In total she collects

$\ \left(1\dfrac{3}{4}+\dfrac{3}{4}+\dfrac{1}{4}+2\dfrac{2}{4}+1\right)=\ \left(1+2+1+\dfrac{3}{4}+\dfrac{3}{4}+\dfrac{1}{4}+\dfrac{2}{4}\right)=\ \left(4+\dfrac{9}{4}\right)=\\ \\\ \left(4+2\dfrac{1}{4}\right)=\ 6\dfrac{1}{4}$

Note that

$\ 6\dfrac{1}{4}=\ 6.25$ ($6 and 25 cents)

Now check in decimals:

$\ 1\dfrac{3}{4}=\ 1.75\\ \\\ \dfrac{3}{4}=\ 0.75\\ \\\ \dfrac{1}{4}=\ 0.25\\ \\\ 2\dfrac{2}{4}=\ 2.50\\ \\\ 1=\ 1$

So, the sum is

$\ 1.75+\ 0.75+\ 0.25+\ 2.50+\ 1=\ 1.75+\ 1+\ 3.50=\ 1.75+\ 4.50=\ 6.25$
