To find when Mubashir and Ali will both exercise on the same day again, we need to calculate the Least Common Multiple (LCM) of their exercise days:
Mubashir: every 8 days
Ali: every 4 days
LCM of 8 and 4 = 8
They will both exercise again on the same day after 8 days.
3/4 = 0.75 and 5/4 = 1.25, so clearly 3/4 is less than 5/4.
Comparing fractions with the same denominator is easy — compare the numerators directly.
The multiplication inverse (or reciprocal) of 3/5 is:
5/3
When you multiply a fraction by its reciprocal, the result is 1:
(3/5) × (5/3) = 1
The answer is 5/3.
Let's denote the number as x.
Step 1: Formulate the equation based on the given information
(4/9)x = 12
Step 2: Solve for x
x = 12 * (9/4)
x = 3 * 9
x = 27
The empty set is a set with no elements.
It is denoted by { } or Ø.
Current temperature is -3°C, and it drops by 4°C.
So, -3 - 4 = -7°C — the new temperature.
n(A × B) = n(A) × n(B) = 3 × 4 = 12.
To evaluate the expression, follow the order of operations:
Multiply 2 and 3: 2 × 3 = 6
Subtract 5 from 4: 4 - 5 = -1
Divide -1 by -1: -1 ÷ -1 = 1
Add 6 and 1: 6 + 1 = 7
