Answer:
х – 9 = +9
Step-by-step explanation:
Answer:
(800 x 9) + (10 x 9)
Step-by-step explanation:
Find out what 810 x 9 is:
810 x 9 = 7290
Then see which expression has the same answer. Personally I'd check all of them, but luckily the first expression is the correct one so you don't need to go through the rest (since it only asks for one correct expression):
(800 x 9) = 7200
(10 x 9) = 90
7200 + 90 = 7290
Lol the answer is 11 of course
Say, for example, you have an improper fraction (it usually is if you're trying to convert to a mixed number) like: 55/7
You would take the highest number that is divisible by the denominator, which in this case is 7 (7x7=49; 7x8 would be 56 and we don't want that)
You subtract the number you got (49) from the original numerator (55).
That will give you 6.
Now, you put the whole number (7) before the fraction (6/7)
