Answer:
6 3/4
Step-by-step explanation:
to write 54/8 into the mixed number and in the simplest form
we first simpify 54/8 which is 27/4
to convert 27/4 into a mixed number we first see how many times does 4 goes into 27 with the remainder. 4 goes into 27 6 times with the remainder of 3. 4 goes into 27 6 times so, 6 will be the whole part 3 remainder will be the numerator and 4 will be the denominator. like 6
Answer:
5 1/5 miles
Step-by-step explanation:
Given that :
Library is located halfway between park and home ;
Distance between library and park = 1 3/10 miles
Hence, total distance between park and home :
1 3/10 + 1 3/10 = 2 6/10
The distance driven :
Home to park ; park back home
2 6/10 + 2 6/10 = 4 12/10
4 + 12/10 = 4 + 1 2/10
= 5 2/10
= 5 1/5 miles
Answer: -1
Explanation: The subscript (3) under 6 has no value so 6 subscript 3 is just 6. Use BEDMAS to solve for the equation (Brackets, Exponents, Division, Multiplication, Addition, Subtraction)
1. 6 x 2 - 24 / square root 16 + (8)
2. 6 x 2 - 24 / 4 + 8
3. 6 x 2 - 24 / 12
4. 12 - 24 / 12
5. -12 / 12
6. -1
Therefore the answer is -1.
