Answers & Comments
4-5(3)-(6÷2)(8)+7*8
We can use the order of operations to solve this equation. First, we perform the operations inside parentheses:
4-5(3)-(6÷2)(8)+78
= 4-5(3)-(3)(8)+78
Then, we perform the operations of multiplication and division:
4-5(3)-(3)(8)+78
= 4-5(3)-24+78
= 4-15-24+78
= -11-24+78
= -35+7*8
Then, we perform the remaining operations of multiplication and addition:
-35+7*8
= -35+56
= 21
So the answer is 21.
5/6÷2/5
We can use the order of operations to solve this equation. First, we perform the operations of division:
5/6÷2/5
= 5/(6÷2)/5
= 5/3/5
Then, we perform the remaining operation of division:
5/3/5
= (5/3)/5
= 5/15
= 1/3
So the answer is 1/3.
689÷35
We can use long division to solve this equation:
689
35 )689
29
29
So the answer is 19 with a remainder of 29.
3892*892
We can use multiplication to solve this equation:
3892892
= 3892800+3892*92
= 3113,600+358,544
= 3,472,144
So the answer is 3,472,144.
5.089 thousandths + 7.23 hundredths
We can add these decimals by aligning the decimal points and adding the digits:
5.089
+7.230
12.319
So the answer is 12.319.
4.790*3.802
We can use multiplication to solve this equation:
4.7903.802
= 4.7903+4.790*0.802
= 14.37+3.863
= 18.233
So the answer is 18.233.
3/4-7/5 = N
We can solve this equation by finding a common denominator and then subtracting the numerators:
3/4-7/5 = N
(3/4)(5/5)-(7/5)(4/4) = N
(35)/(45)-(74)/(54) = N
15/20-28/20 = N
(15-28)/20 = N
-13/20 = N
So the answer is -13/20.
7.890÷0.61
We can use division to solve this equation:
7.890÷0.61
= 7.890/0.61
= 12.902
So the answer is 12.902.
