Answer:
To find the lowest form of 28 upon 36, we need to simplify or reduce the fraction to its lowest terms. This can be done by finding the greatest common factor (GCF) of the numerator (28) and the denominator (36) and dividing both by it.
First, we can find the prime factors of 28 and 36:
28 = 2 × 2 × 7
36 = 2 × 2 × 3 × 3
Next, we can identify the common factors, which are 2 and 2.
To find the greatest common factor, we need to multiply the common factors together. In this case, 2 × 2 = 4, so the greatest common factor is 4.
Now we can divide both the numerator and the denominator by the GCF:
28 ÷ 4 = 7
36 ÷ 4 = 9
Therefore, the lowest form of 28 upon 36 is 7/9.
