Question

4*3 1/2-(1 1/2+4 3/5)

Answer 1

$4\cdot 3\frac{1}{2}-(1\frac{1}{2}+4\frac{3}{5})=4\cdot \frac{7}{2}-( \frac{3}{2}+\frac{23}{5})=2\cdot 7-\frac{3\cdot 5+23\cdot 2}{2\cdot 5}=\\\\=14-\frac{61}{10}=14-6,1=7,9$

Answer 2

4 *(7/2) - ( (3/2) +
+(23/5) ) =
=14 - (15 + 46)/10 =
= 14 - 6,1 = 7,9

Answer 3

To calculate the expression, follow these steps:

Step 1: Perform the addition inside the parentheses first. Step 2: Perform the multiplication and division from left to right.

Let's start:

Step 1: Addition inside parentheses 1 1/2 + 4 3/5 = (1 + 4) + (1/2 + 3/5) = 5 + (5/10 + 6/10) = 5 + 11/10 = 5 + 1 1/10 = 6 1/10

Step 2: Perform the remaining operations from left to right 4 * 3 1/2 - 6 1/10

Next, convert 3 1/2 to an improper fraction: 3 1/2 = (2 * 3) + 1 = 7/2

Now, we have: 4 * 7/2 - 6 1/10

Now, multiply: 4 * 7/2 = 28/2 = 14

Subtract: 14 - 6 1/10

Convert 6 1/10 to an improper fraction: 6 1/10 = (10 * 6) + 1 = 61/10

Now, we have: 14 - 61/10

To subtract, find a common denominator: 14 = 140/10

Now, we have: 140/10 - 61/10

Subtract the fractions: (140 - 61)/10 = 79/10

The final result is 79/10, which can also be expressed as a mixed number: 7 9/10.
