To solve this expression, we can use the distributive property of multiplication over addition.

First, let's simplify the expression inside the parentheses:

\( (35 \%+25 \%) = 60 \% \)

\( (35 \%+40 \%) = 75 \% \)

Now, we can multiply these two simplified expressions:

\( 60 \% \times 75 \% = 0.6 \times 0.75 = 0.45 \)

Therefore, \( (35 \%+25 \%)(35 \%+40 \%) = 0.45 \) or 45%.

Answer:


\sf \text{Decimal: } 0.45


\sf \text{Fraction: } (9)/(20)


\sf \text{Percentage: } 45\%

Explanation:


\sf \left((7)/(20) + (2)/(5)\right) \left((7)/(20) + (1)/(4)\right)

Find a common denominator for each set of fractions.

The common denominator for
\sf 20 and
\sf 5 is
\sf 20.

So, rewrite the expression with a common denominator of
\sf 20:


\sf \left((7)/(20) + (2 \cdot 4)/(5\cdot 4 )\right) \left((7)/(20) + (1\cdot 5 )/(4\cdot 5)\right)


\sf \left((7)/(20) + (8)/(20)\right) \left((7)/(20) + (5)/(20)\right)

Add the fractions inside each set of parentheses:


\sf \left((7+8)/(20)\right) \left((7+5)/(20)\right)


\sf \left((15)/(20)\right) \left((12)/(20)\right)

Multiply the two fractions:


\sf (15)/(20) * (12)/(20) = (180)/(400)

Simplify the fraction:


\sf (180)/(400) = (9)/(20)

Now, let's express the result as a decimal and a percentage:

Decimal:
\sf (9)/(20) \approx 0.45

Percentage:
\sf (9)/(20) * 100\% = 45\%

So, the final answers are:


\sf \text{Decimal: } 0.45


\sf \text{Fraction: } (9)/(20)


\sf \text{Percentage: } 45\%
