First convert to an improper fraction:
-5 2/7 = -37/7
-2 1/7 = -15/7
So now you have -37/7 / -15/7
When you divide with a fraction, you just flip the numerator and denominator of the divisor and multiply instead, so
-37/7 * -7/15 = 37/15 which would be in "improper" form.
To convert it to mixed number form it would be 2 7/15
Answer:
38.5 cm
Step-by-step explanation:
1. To find the radius divide 7 by 2 which is 3.5
2. Then multiply 3.5 by itself which is 12.25
3. Next multiply 12.25 by 3.14 ( 3.14 =
= pi )
4. Lastly your answer will be 38.5
Answer:
The second and third equations are correct.
Step-by-step explanation:
Note that the equations are all the same, with the exception of the math operation (=,>,<,
, etc.). Let's do one calculation and then decide which of the statements is true.
The components may be simplified by separating the numbers from the exponents and doing the calculations separately:
(2.06x10^-2)(1.88x10^-1) becomes (2.06*1.88)*(10^-2 * 10^-1)
Left Side:
(2.06*1.88) = 3.91
(10^-2 * 10^-1) = 10^-3 [The exponents add when multiplying]
(2.06x10^-2)(1.88x10^-1) = 3.91x10^-3
Right side:
(7.69/2.3) = 3.343
(10^-2)/(10^-5) = 10^3 [The bottom exponent is subtracted from the top. ( -2 - (-5)) = 3 ]
(7.69x10^-2)/(2.3x10^-5) = 3.343x10^3
For all equations:
LEFT RIGHT
3.91x10^-3 3.343x10^3
We can now answer the question. Is the left side (3.91x10^-3 )
A. <
B. =>
C. >, or
D. =
to the right side (3.343x10^3)
We can drop the 10^-3 to make the comparison simpler, since it is the same on both sides. Think of it as dividing both sides by 10^3.
Correct?
A. 3.91 < 3.34 NO
B. 3.91 => 3.34 YES
C. 3.91 > 3.34, or YES
D. 3.91 = 3.34 NO
60 hundredths is 60 percent. You can also move the decimal point two places to the right to find the percent equivalent. To write 0.6 as a fraction, you read the decimal, 6 tenths, and write 6 tenths in fraction form. Simplify the fraction by dividing the numerator and denominator by 2, a common factor.
Answer:
40 gal / 72 gal
lets reduce
20 / 36
(yeah, the gal reduce away as well)
reduce further
10/18
and further
5/9
done :)
