Answer:

3 7/8

Step-by-step explanation:

_____ + 5 3/4 = 9 5/8

x + 5 3/4 = 9 5/8

Subtract 5 3/4 from each side

x + 5 3/4 - 5 3/4 = 9 5/8 - 5 3/4

x = 9 5/8 - 5 3/4

Get a common denominator of 8

5 3/4 *2/2 = 5 6/8

x = 9 5/8 - 5 6/8

We need to borrow 1 from the 9 in the form of 8/8

x= 8 + 8/8+ 5/8 - 5 6/8

x = 8  13/8 - 5 6/8

  = 3 7/8

Answer:

\Large \boxed{3\frac{7}{8}}

Step-by-step explanation:

Let the missing value be x.

x+5\frac{3}{4} =9 \frac{5}{8}

Subtract 5 \frac{3}{4} from both sides.

x =9 \frac{5}{8} - 5 \frac{3}{4}

Converting the mixed fractions to improper fractions.

x =\frac{77}{8} - \frac{23}{4}

Make denominators equal and subtract.

x =\frac{77}{8} - \frac{46}{8}

x =\frac{77-46}{8}

x =\frac{31}{8}

Converting the improper fraction into a mixed fraction.

x=3\frac{7}{8}

<h3>I'll teach you how to solve 6.71 - 2.2 × 2.1 + 0.5^2</h3>

-----------------------------------------------------------------

Multiply the numbers: 2.2*2.1= 4.62

6.71-4.62+0.5^2

Subtract the numbers: 6.71-4.62= 2.09

0.5^2+2.09

0.5^2 = 0.25

0.25+2.09

Add the numbers:

0.25+2.09=  2.34
