List the fractions and decimals in order from least to greatest...
alina1380 [7]
In order to list them from least to greatest is by finding the smallest number first. Negative numbers are always less than positive, so -3/8 and -0.65 have to be ordered first. -3/8 or -0.38 is greater than -0.65, so -0.65 would be first. Then the next negative which is -0.65 comes next. the last two fractions are 2/4 or 1/2 or 0.5 and 5/16 or 0.31. 0.5 is greater than 0.31, so the order is -0.65, -3/8, 5/16, and 2/4. Hope this helps!

A shop sells chocolate, vanilla and strawberry ice creams. 45% of the ice creams sold are vanilla, and 1/4 are strawberry. What
Alinara [238K]

Answer:

Step-by-step explanation:

Total percentage = 100%

And we know that proportions of Vanilla +chocolate +strawberry = 100%

Proportion of Vanilla = 45%

Proportion of Strawberry = 1/4  *100 = 25%

Let proportion of chocolate be represented by variable C;

So, 45% +25% + C = 100%

65% +C = 100%

Subtract 65% from both sides to solve for C;

C=100% - 65%

C = 35%

Therefore there is 35% of chocolate  in the shop.
