A restaurant cook made 10 pieces of toast. She put butter on 6 of them. What fraction of the pieces of toast have butter now?

6/10 or 3/5

Step-by-step explanation:

6 out of the 10 pieces have butter on them, so we can write it as

6/10

6/10 can be simplified, because both the numerator and denominator can be divide by 2

3/5

So, 6/10 or 3/5 pieces of toast have butter on them

Hope this helps! :)

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
