\][/tex]


Sagot :

Let's solve this math problem step by step.

First, we have four fractions:
[tex]\[ \frac{7}{10}, \frac{8}{3}, \frac{7}{2}, \frac{29}{8} \][/tex]

To combine these fractions, we need to perform the following operations:
[tex]\[ \frac{7}{10} + \frac{8}{3} + \frac{7}{2} - \frac{29}{8} \][/tex]

Let's start by converting these fractions into decimal form to make it easier to add and subtract them.

1. Convert [tex]\( \frac{7}{10} \)[/tex] into a decimal:
[tex]\[ \frac{7}{10} = 0.7 \][/tex]

2. Convert [tex]\( \frac{8}{3} \)[/tex] into a decimal:
[tex]\[ \frac{8}{3} \approx 2.6666666666666665 \][/tex]

3. Convert [tex]\( \frac{7}{2} \)[/tex] into a decimal:
[tex]\[ \frac{7}{2} = 3.5 \][/tex]

4. Convert [tex]\( \frac{29}{8} \)[/tex] into a decimal:
[tex]\[ \frac{29}{8} = 3.625 \][/tex]

Now we add the first three fractions and then subtract the fourth one.

First, add [tex]\( 0.7 \)[/tex] and [tex]\( 2.6666666666666665 \)[/tex]:
[tex]\[ 0.7 + 2.6666666666666665 = 3.3666666666666663 \][/tex]

Next, add [tex]\( 3.3666666666666663 \)[/tex] and [tex]\( 3.5 \)[/tex]:
[tex]\[ 3.3666666666666663 + 3.5 = 6.866666666666666 \][/tex]

Finally, subtract [tex]\( 3.625 \)[/tex] from [tex]\( 6.866666666666666 \)[/tex]:
[tex]\[ 6.866666666666666 - 3.625 = 3.2416666666666663 \][/tex]

Therefore, the final result is:
[tex]\[ \frac{7}{10} + \frac{8}{3} + \frac{7}{2} - \frac{29}{8} = 3.2416666666666663 \][/tex]

So, the answer to the problem is:
[tex]\[ \boxed{3.2416666666666663} \][/tex]
