Multiply the first number by 3 to get the second number, subtract 5 from the second number to get the third number, multiply the third number by 3 to get the fourth number, subtract 5 from the fourth number to get the fifth number, ... So the pattern is: starting number, previous x 3, previous - 5, previous x 3, previous - 5, previous x 3

2 and 5 if you multiply them. 50 and 5 if you divide them. 5 and 5 if you add them. 15 and 5 if you subtract them.
To subtract a number, re write the problem to add the opposite of the number. Example: 5-11 5+(-11) <-Rewrite the problem to add the opposite of the number. 11-5 <-Find the difference of their absolute values. 6 <-Subtract -6 <- -11has the greater absolute value, the answer takes the negative sign. hope this helps.

From the Fahrenheit temperature, subtract 32. Then multiply by 5/9.C = (5/9) (F - 32)From the Fahrenheit temperature, subtract 32. Then multiply by 5/9.C = (5/9) (F - 32)From the Fahrenheit temperature, subtract 32. Then multiply by 5/9.C = (5/9) (F - 32)From the Fahrenheit temperature, subtract 32. Then multiply by 5/9.C = (5/9) (F - 32)
Convert the whole number to a fraction with the same numerator and subtract: 3-4/5 3=15/5 15/5-4/5=11/5
