-3/5+(8/35)=
-14/35 + (8/35) = -6/35
74.0754 = 74.08 to the nearest hundredth
first one. No, incorrect, very
Second, yes, but precision is ridiculous. Nearest hundredth is 74.08 oz
Let's go through each calculation step by step to verify the answers:
1. -3/5 + 8/35:
To add these fractions, you need to find a common denominator. The least common multiple (LCM) of 5 and 35 is 35. So, you need to transform the fractions to have a denominator of 35:
(-3/5) x (7/7) = -21/35
(8/35)
Now, you can add the fractions together:
-21/35 + 8/35 = -13/35, which simplifies to -0.37142857.
So, the correct answer for -3/5 + 8/35 is -0.37142857.
2. 2 + 4.375:
Adding the whole number 2 with the decimal number 4.375:
2 + 4.375 = 6.375
So, the correct answer for 2 + 4.375 is indeed 6.375.
3. Converting kilograms to ounces:
To convert kilograms to ounces, you need to use the conversion factor: 1 kilogram = 35.2739619 ounces.
For 2.1 kilograms:
2.1 kilograms x 35.2739619 ounces/kilogram = 73.98432099 ounces
Rounding this to the nearest hundredth, we have:
73.98432099 ≈ 73.98
So, the correct answer for 2.1 kilograms to the nearest hundredth in ounces is 73.98, not 0.800.
In summary:
- -3/5 + 8/35 = -0.37142857
- 2 + 4.375 = 6.375
- 2.1 kilograms ≈ 73.98 ounces
