Ответ:
Okay, so first you need to convert the mixed numbers into improper fractions:
= 2 1/6 = 13/6
= 4 1/2 = 9/2
= 13/6*9/2
= 13*9/6*2
= 13*3*3/6*2
= 13*3*3/3*2*2
= 13*3/2*2
= 39/2^2
= 39/4
39/4 = 9 3/4
Ответ:
9 3/4
Step-by-step explanation:
First you would want to multiply the whole number with their denominators and then add the numerator to that. 2*6+1 and 4*2+1 Then you keep the original denominator at the bottom of the fraction.
2*6+1/6 4*2+1/2 ---> 13/6 x 9/2
You would then simplify the crossing numbers 6 and 9. They both can be divided by three.
13/2 x 3/2 = 39/4
Now you would do long division where you divide 39 by 4
4 goes into 39 nine times subtracting 36 from 39.
You then end up with 1 which becomes you numerator, 4 is the new denominator and 9 is the whole number.
Ответ:
the difference is that the two equations are for diffrent prisms and that when you use the sine ratio it's for a right triangle.
