Question

4умножить15+24:3+5=64 раствте скобки чтобы получилось 64

Answer 1

(4×15)+(28÷(3+5))=64
60+(28÷8)=64
60+4=64
64=64.

Answer 2

To get the expression to equal 64 by adding parentheses, you can do the following:

4 * (15 + 24) / (3 + 5) = 64

Let's break it down step by step:

1. Perform the addition inside the first set of parentheses: 15 + 24 = 39.
2. Perform the addition inside the second set of parentheses: 3 + 5 = 8.
3. Perform the division: 39 / 8 = 4.875.
4. Finally, multiply by 4: 4 * 4.875 = 19.5.

The expression is not equal to 64, so let's try a different arrangement:

(4 * 15) + (24 / 3) + 5 = 64

1. Perform the multiplication inside the first set of parentheses: 4 * 15 = 60.
2. Perform the division inside the second set of parentheses: 24 / 3 = 8.
3. Add the results together: 60 + 8 + 5 = 73.

This arrangement also does not equal 64. Let's try one more:

(4 * 15) + (24 : (3 + 5)) = 64

1. Perform the multiplication inside the first set of parentheses: 4 * 15 = 60.
2. Perform the addition inside the second set of parentheses: 3 + 5 = 8.
3. Perform the division: 24 / 8 = 3.
4. Add the results together: 60 + 3 = 63.

Unfortunately, this arrangement also does not equal 64. It seems that there is no way to arrange the expression using parentheses to make it equal 64.
