Explanation

1. Convert all fractions to a common denominator (8):

   • $\frac{3}{4}=\frac{6}{8}$

   • $\frac{5}{8}=\frac{5}{8}$

   • $\frac{1}{2}=\frac{4}{8}$

2. Perform the calculation:

   • $\frac{6}{8}+\frac{5}{8}-\frac{4}{8}=\frac{7}{8}$

3. Convert $\frac{7}{8}$ to decimal:

   • $\frac{7}{8}=0.875\approx 0.87$

Explanation

Given: you have a bowl with six apples and you take away four

To find: how many do you have

Apples in bowls =6

taken away apples =4

Thus you have 4 apples and the bowl has 2 apples

Explanation

The difference between +16 and +28 is:

+16 - (+28) = +16 - 28 = -12

Explanation

(+5) - (+7) = 5 - 7 = -2

Subtracting a larger positive number from a smaller one gives a negative result.

Explanation

The number that is 200 more than 546 is:

546 + 200 = 746

So, 746 is 200 more than 546.

Explanation

To evaluate the expression 7/12 - 3/8 - 4/9:

Step 1: Find the least common multiple (LCM) of 12, 8, and 9.

The LCM of 12, 8, and 9 is 72.

Step 2: Convert each fraction to have a denominator of 72.

7/12 = (7 × 6) / (12 × 6) = 42/72

3/8 = (3 × 9) / (8 × 9) = 27/72

4/9 = (4 × 8) / (9 × 8) = 32/72

Step 3: Subtract the fractions.

42/72 - 27/72 - 32/72 = (42 - 27 - 32) / 72

= (42 - 59) / 72

= -17/72

Explanation

Subtracting a negative is the same as adding: (-0.9) - (-0.9) = -0.9 + 0.9.

The result is 0.

Explanation

Greatest 5-digit number = 99999

Smallest 4-digit number = 1000

So, 99999 − 1000 = 98999

Explanation

Explanation

The smallest two-digit number is 10.

The largest two-digit number is 99.

Subtract the smallest from the largest:

99 - 10 = 89
