Answer:
Step-by-step explanation:
To make an improper fraction, make the whole number into a fraction with the denominator 6. We do this because we want the fraction and the whole number to have the same denominator, so we can later add them together.
To do this, multiply 4 by 6:
* =
Then, add and together
+ =
Answer:
1⅞ - 1½ ≈ ½
Step-by-step explanation:
Estimation is mental arithmetic. Practice until you can do this in your head.
Here's one way to estimate with mxed numbers.
Step 1. Separate into whole number and fractional parts
1⅞ - 1½ = 1 + ⅞ - 1 - ½
Step 2. Solve the whole number parts
1 - 1 = 0
Step 3. Solve the fraction parts by estimating.
We will round to the nearest ½, so we should round up a number greater than ¾.
(a) ⅞ is greater than ⁶/₈ (¾), so we round it up to ⁸/₈:
⅞ - ½ ≈ ⁸/₈ - ½
(b) Convert each fraction to a common denominator.
We can write ⁸/₈ as ²/₂
⁸/₈ - ½ = ²/₂ - ½
(c) Solve the fraction part
²/₂ - ½ = ½
Step 4. Combine the whole and fraction parts
0 + ½ = ½
So, 1⅞ - 1½ ≈ ½
So first you have to simply and evaluate the expression . it becomes x>2. plot the point on 2 using an open circle going to the right .
