Answer:

2 $\frac{3}{4}$ + -2 $\frac{3}{4}$ = 0

Step-by-step explanation:

1st step convert into improper fraction:

===> 2 $\frac{3}{4}$ + -2 $\frac{3}{4}$

===> $\frac{16}{4}$ + $-\frac{16}{4}$

2nd step now adding the numbers:

( Plus sign and minus sign multiplies and hence the plus sign changes to minus)

===> $\frac{16-16}{4}$

Therefore the sum of 2 $\frac{3}{4}$ + -2 $\frac{3}{4}$ = 0

M+1 3/8=5 What does m equal?

Arte-miy333 [17]

$\text{ The value of m is equal to 3.625 or }\frac{29}{8} \text{ or } 3\frac{5}{8}$

Solution:

Given that we have to find the value of "m"

Given expression is:

$m + 1\frac{3}{8} = 5$

Let us first convert the mixed fraction to improper fraction

Steps to follow:

Divide the numerator by the denominator.

Write down the whole number answer.

Then write down any remainder above the denominator.

Therefore,

$1\frac{3}{8}=\frac{8 \times 1+3}{8} = \frac{8+3}{8} = \frac{11}{8}$

Now the expression becomes,

$m + \frac{11}{8} = 5$

Keep the variable "m" on L.H.S and move the constant to R.H.S

$m = 5 - \frac{11}{8}\\\\m = \frac{5 \times 8 -11}{8}\\\\m = \frac{40-11}{8}\\\\m = \frac{29}{8}\\\\\text{In mixed fractions, we can write as }\\\\m = \frac{29}{8} = 3\frac{5}{8}$

Thus value of m is equal to 3.625 or $\frac{29}{8} \text{ or } 3\frac{5}{8}$
