Answer: 6 to 1, 6: 1 or
Explanation:
In mathematics, the purpose of a ratio is to compare the quantity or values of two different items. For example, if in a recipe 1 spoon of sugar needs to be added for every 3 spoons of water the ratio of spoons of sugar to water is 1 to 3.
In this context, the first step is to find the values of the two items compared. In the case presented these items are the eyes in a spider vs the number of spiders. Also, it is known each spider has 6 eyes. This means the ratio of eyes to spides is 6 to 1, which means for each 6 eyes there is 1 spider. Moreover, this ratio can be written as 6 to 1, using a colon as 6: 1, or as a fraction .
The weight of the hamburger is 160g after two bites.
Each bite takes away 20% of the weight of the burger, so we'll divide the initial weight by a percentage to find the weight before the bite.
The starting weight is 160g. Because 20% of the weight was removed from a bite, we'll divide this weight by the percentage of the burger remaining after the bite:
80% of the burger is left after a bite. Convert this fraction into a decimal by dividing by 100:
Divide the initial weight by this decimal:
The weight of the burger before the second bite was 200.
We'll do the same procedure for the first bite. The initial weight is 200, and there is 80% of the burger remaining after the first bite. Because 80% is 0.8 in decimal form, divide 200 by 0.8:
The starting weight of the burger before the bites was 250 grams.
