belinda used her calculator to find the decimal for the fraction 21/28.When she entered 21/28, the calculator gave an answer that looked familiar. Why do you think she recognized it?
It said 0.75 (or 3/4),
which is a very common fraction, so she had probably seen it before.
Is that what you mean?

Belinda might have recognized the answer given by her calculator because it is a simplified form or equivalent decimal of the fraction 21/28.
To find the decimal for a fraction, you would typically divide the numerator (top number) by the denominator (bottom number). In this case, dividing 21 by 28 would give you a decimal value.
To find out the exact decimal value for the fraction 21/28, Belinda could do the following steps:
1. Divide 21 by 28: 21 ÷ 28 = 0.75
The resulting decimal is 0.75. However, it is essential to note that 0.75 can be simplified further by finding the greatest common divisor (GCD) for both the numerator and the denominator.
The GCD for 21 and 28 is 7. By dividing both the numerator and the denominator by 7, we can simplify the fraction to its lowest terms:
2. Simplify the fraction: 21 ÷ 7 / 28 ÷ 7 = 3/4
So, the simplified form of 0.75 is 3/4. This value is often recognized as a commonly used fraction, especially in measurements or comparisons, which is why Belinda might have found it familiar when she entered 21/28 into her calculator.
