1 2/5 x 3 4/5 = 5.32 -- with calculator
----------------------------------------------------
You can change mixed fractions to improper fractions.
1 2/5 = 1 x 5 + 2 = 7 = 7/5
3 4/5 = 3 x 5 + 4 = 19 = 19/5
7/5 x 19/5 = 133/25 = 5.32
-----------------------------------------
To make sure you can then turn the improper fractions to decimals.
7/5 = 1.4
19/5 = 3.8
1.4 x 3.8 = 5.32
--------------------------
Whenever I get mixed fraction questions, I always check it in these different excess ways just to make sure :3 Hope it helped..
Answer:
Step-by-step explanation:
hello :
ax+b =4x+9 so a=4 and b=9
1. 4i x -10i = -40ii
ii = i^2 = -1
-40*-1 = 40
2. -6-9 = -15
5i- - 5i = 5i + 5i = 10i
answer = -15 +10i
3. raise both sides to the 3rd, and solve for x. x = -12
4. the equation would be x^2+36 =0
