Answer:
The number is 0.2
Step-by-step explanation:
Write an equation for it:
Say that the number was called x
2(x +8) =16.4
Brain added 8 to the number (x) and then doubled it which is the 2
Times out the brackets 2x + 16 = 16.4
Take away 16 from both sides
2x = 0.4
0.4 / 2 = 0.2
Answer:
2 and 3
Step-by-step explanation:
9/4=2.25
You could just multiply the whole number with the numerator and then divide the answer by the denominator. Or you could write the whole number over 1, and then simplify the numbers before multiplying straight across.
2/3 x 36
2/3 x 36/1
2/1 x 12/1 (simplified the 3 and the 36)
24/1=24 (just multiplied across)
