When any number is multiplied by 0, the result is always 0. In this case, 83 multiplied by 0 would also equal 0. Therefore, the correct answer is 0.

To find the value of b in the equation 3 + 4b = 15, we need to isolate the variable b. By subtracting 3 from both sides of the equation, we get 4b = 12. Then, dividing both sides by 4, we find that b = 3.

The percentage of 3/20 is 15%. To find the percentage, we divide the numerator (3) by the denominator (20) and then multiply the result by 100. In this case, 3 divided by 20 is 0.15, and when multiplied by 100, it gives us 15%.

The perimeter of a rectangle is calculated by adding the lengths of all its sides. In this case, the length is given as 36 cm and the breadth is given as 24 cm. To calculate the perimeter, we add twice the length and twice the breadth: 2(36 cm) + 2(24 cm) = 72 cm + 48 cm = 120 cm. Therefore, the correct answer is 120 cm.

The given expression involves adding a negative number (-8) and a positive number (+2), which results in a negative number (-6). Then, subtracting a negative number (-6) from the previous result gives a positive number (0). Therefore, the correct answer is (0).

The given expression represents the addition of two fractions, 2/3 and 1/4. To add fractions, we need to find a common denominator, which in this case is 12. We then convert both fractions to have a denominator of 12, resulting in 8/12 and 3/12. Adding these fractions together gives us 11/12. Therefore, the correct answer is 11/12.

The correct answer is 0.07 because 7% of 1 is equal to 0.07. To find this, we can convert 7% to a decimal by dividing it by 100, which gives us 0.07. Then, we multiply this decimal by 1, resulting in 0.07.

According to BODMAS, which stands for Brackets, Order (exponents and roots), Division and Multiplication (from left to right), and Addition and Subtraction (from left to right), brackets should be evaluated first. This means that any calculations within brackets should be done before any other operations. Therefore, brackets come first according to BODMAS.

To solve for the number that goes in the blank in the equation:



_/5 - 7/10 = 1/10



You can start by isolating the unknown number on one side of the equation. Here's how to do it step by step:



1. Add 7/10 to both sides of the equation to move the -7/10 to the right side:

   

   _/5 = 1/10 + 7/10



2. Combine the fractions on the right side:



   _/5 = 8/10



3. Simplify the fraction on the right side by dividing both the numerator and denominator by their greatest common divisor, which is 2:



   _/5 = (8/2) / (10/2)

   _/5 = 4/5



So, the number that goes in the blank is 4.

The given equation is -5 = X + 7. To solve for X, we need to isolate it on one side of the equation. By subtracting 7 from both sides, we get X = -12. Therefore, the correct answer is -12.
