A plant was 4/5 meter tall. Then 1/2 meter was cut off. When the height of the plant was last measured it had grown back1/10 meter. What was the height of the plant when it was last measured?

2/5 or 0.4

Step-by-step explanation:

4/5 - 1/2 + 1/10 =

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9
