Communicate Mathematical Ideas Julie got 21 of the 23 questions on her math test correct. She got 29 of the 32 questions on her science test correct. On which test did she get a higher score? Can you compare the fractions and by comparing 29 and 21? Explain. How can Julie compare her scores?
Answers
21/23
21*32=672 and 23*32=736, so 672/736
29/32
29*23=667 and 32*23=736, so 667/736
672/736 is greater than 667/736

We can say this is a simple multiplication operation, which is one of four basic operations, i.e.,
- addition,
- subtraction,
- multiplication, and
- division.
The case we face is only a multiplication, not accompanied by another operation.
Ted said that 3 tenths multiplied by 100 equals 300 thousandths. Let's check the truth.
However, 3 tenths are a fraction less than 1 so if multiplied by 100 will produce a number that is less than 100.
We firmly say, 3 tenths multiplied by 100 do not equal 300 thousandths. Ted is not correct.
Let's calculate the correct result.
100 can be divisible by 10, or cross out zeros at 100 and 10.
Hence, the correct result is

Step-by-step explanation:
If you let b = x^2 the problem becomes a whole lot easier. Note that x = √b
x^2 + x - 12
Now factor this trinomial.
(x + 4)(x - 3)
Now put b back into the equation
(√b + 4)(√b - 3)
