b. 6.72
c. 6.33
d. 1.43​

Answer 1

Given: $6 +7/10 + 2/100 = ?$

We have to solve the above expression.

• As we know that adding two or more numbers together is known as an addition.
• The addition is denoted by a symbol(+).

Following are the properties of addition:

1. Identity property of zero.
2. Inverse property.
3. Commutative property.
4. Associative property.

We are solving in the following way:

We have,

$6 +7/10 + 2/100 = ?$

making the denominator same:

$=>\frac{6}{1} \times \frac{100}{100} +\frac{7}{10} \times\frac{10}{10}\times\frac{2}{100}$

Multiplying the above:

$=>\frac{600}{100} +\frac{70}{100} \times\frac{2}{100} \\\\=>\frac{600+70+2}{100} \\\\=>\frac{672}{100} \\\\=>\frac{168}{25}$

Solving the above expression further, we get

$=>6.72$

Hence, we get the solution is$6.72$.
