2 6/7 - 5/7 + 1 4/7
To calculate 2 6/7 - 5/7 + 1 4/7, we'll first convert the mixed numbers to improper fractions.
2 6/7 can be converted to (7*2 + 6)/7 = 20/7.
1 4/7 can be converted to (7*1 + 4)/7 = 11/7.
Now, we can perform the calculations:
20/7 - 5/7 + 11/7 = (20 - 5 + 11)/7 = 26/7.
Therefore, 2 6/7 - 5/7 + 1 4/7 = 26/7.
include the remeinder
To include the remainder, we can express the result as a mixed number.
26/7 can be written as 3, with a remainder of 5/7.
Therefore, 2 6/7 - 5/7 + 1 4/7 = 3 5/7.
54 + 18.28 + 33.94
To add 54, 18.28, and 33.94 together, we can simply add these numbers.
54 + 18.28 + 33.94 = 106.22
0.4 - 0.2 + 0.8 + (-0.8)
To evaluate 0.4 - 0.2 + 0.8 + (-0.8), we can directly add up the numbers.
0.4 - 0.2 + 0.8 + (-0.8) = 0.4 + 0.8 - 0.2 - 0.8 = 0.6 - 0.2 = 0.4.
Thus, 0.4 - 0.2 + 0.8 + (-0.8) equals 0.4.
thats not a chioce
Apologies for the confusion. Let's break it down step by step:
0.4 - 0.2 + 0.8 + (-0.8)
0.4 - 0.2 = 0.2
0.2 + 0.8 = 1.0
1.0 + (-0.8) = 0.2
Therefore, 0.4 - 0.2 + 0.8 + (-0.8) equals 0.2.
To add or subtract mixed numbers, we need to convert them to improper fractions and then perform the operation. Let's break down the given expression step by step:
Step 1: Convert the mixed numbers to improper fractions.
2 6/7 can be written as (2 * 7 + 6)/7 = 20/7.
1 4/7 can be written as (1 * 7 + 4)/7 = 11/7.
Now the expression becomes: 20/7 - 5/7 + 11/7.
Step 2: Add or subtract the fractions.
To add or subtract fractions, we need a common denominator. In this case, the denominator is already the same (7), so we can proceed directly.
20/7 - 5/7 + 11/7 = (20 - 5 + 11)/7 = 26/7.
Step 3: Simplify the fraction, if required.
26/7 cannot be simplified any further. Therefore, the final answer is 26/7.
