Question

0.5 m² : 10cm². express the ratio in lowest terms​

Answer 1

Step-by-step explanation:

It is desirable to write a ratio in its lowest terms as, 15 : 10 = 3 : 2 (dividing both the term by 5). Then the ratio 3 : 2 is in its lowest term, 3 and 2 are co-primes, or their H.C.F. is 1.

Answer 2

\sum\limits_{i=1}^n x_i = x_1 + x_2 + \dots + x_n

i = index of summation

n = upper limit of summation
