Organic Whole Wheat Flour Sells in bags Weighing 2.915 Kg A. How much flour is this when rounded to the nearest tenth B. How much flour is this when rounded to the nearest tenth Explain your thinking

Answers

Answer:

2.9 kg

Step-by-step explanation:

If you round 2.915 to the nearest tenth, it would be 2.9. this is because the number to the right of the 9 (1) is below 5.

The amount of flour after rounded to the nearest tenth will be 2.91 kg.

What is rounding off?

Rounding numbers refers to changing a number's digits such that it approximates a value. The provided number is more simply represented by this value. For instance, 700,000 rather than 698,869 could be used to express a town's population.

Given that;

Organic Whole Wheat Flour Sells in bags Weighing 2.915 Kg.

Now,

Since, Organic Whole Wheat Flour Sells in bags Weighing 2.915 Kg.

We know that;

When we round to the nearest tenth we see the right digit of tenth place if it is less than 5 then write same as number but if the number is greater than 5 then add one on the tenth place number.

Hence,

The amount of flour after rounded to the nearest tenth = 2.9

Because,  1 < 5

Thus, The amount of flour after rounded to the nearest tenth = 2.9 kg
