Study the two pie charts.

What can we write about the difference in relation to oil?


Which is the correct sentence about oil?  A, B or C?

A. Oil production increased to 45%.
B. Oil production increased by 45%
C. Oil production increased 45%.

Is there any difference in the three options?  Share your answer/thoughts below.


The only correct answer is A.
If you write 'by 45%' then the amount would need to be 70% (ie 25% + 45%)
If you write 'increased 45%' then the amount would also need to be 70% (25% + 45%)
