Answer:
70%
Step-by-step explanation:
since 7/10 is 0.7 as a decimal
you can then turn it into a percent by moving the decimal point two spots to the right
70 --> 70%
another way to do it is, to add zeros on both the numerator and denominator
then it is valued at 70/100 
a percent is a number over 100
70 ---> 70%
your answer is 70%
