Decimal Fraction Percentage
3.24 81/25 324%
Step-by-step explanation:
Hello!
When you subtract these numbers, you always first subtract the numbers in the smallest place value. In this case, that would be the .5 and .7. However, since you cannot subtract 7 from 5 without getting a negative number, borrow a one from the place value that is one greater.
Thus, you get:
15 - 7 = 8
Therefore, we know that the ._ digit of our result is .8.
Now, moving on to the next smallest place value (in this case the largest).
You would subtract 7 - 3, however remember earlier that we borrowed a one. When you borrow a one, you must subtract one from the number that it was borrowed from. Therefore, the equation would become 6 - 3.
6 - 3 = 3
Therefore, the ones digit of our result is 3.
Put these two together, and you get your result of 3.8.
Hope this helps!
Answer:
m = 0.449
Step-by-step explanation:
Isolate the variable, m. Note the equal sign, what you do to one side, you do to the other. Remember to do the opposite of PEMDAS.
PEMDAS is the order of operation & =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
First, subtract 2.4 from both sides:
2.4 (-2.4) + 10m = 6.89 (-2.4)
10m = 6.89 - 2.4
10m = 4.49
Divide 10 from both sides:
(10m)/10 = (4.49)/10
m = 4.49/10
m = 0.449
0.449 is your answer for m.
