Answer 1

The sum of 3/10 and 68/100 is 98/100, which is also 0.98 when expressed as a decimal.

Step-by-step explanation:

The sum of 3/10 and 68/100 can be found by converting each fraction to have a common denominator and then adding the numerators. Since the denominators 10 and 100 are not the same, we must find a common denominator to combine these fractions. The smallest common denominator for 10 and 100 is 100.

First, we convert 3/10 into a fraction with a denominator of 100, which gives us 30/100. Next, we can directly add the fractions now that they have the same denominator:

• 30/100 + 68/100 = 98/100

Therefore, the sum of 3/10 and 68/100 is 98/100, which can also be expressed as 0.98.

Answer 2

`\sf(3)/(10)+(68)/(100)`

Convert 3/10 to a fraction over 100. We do this by multiply 10 to the numerator and denominator.


`\sf(3)/(10)\rightarrow(3*10)/(10*10)\rightarrow(30)/(100)`

Now we can add the numerators of the two fractions together and keep the denominator.


`\sf(30)/(100)+(68)/(100)\rightarrow(30+68)/(100)`


`\sf(98)/(100)`

Simplify by dividing 2 to the numerator and denominator:


`\sf(98/2)/(100/2)\rightarrow\boxed{\sf(49)/(50)}`
