Without calculating, is the equation (1.8 x 3) x 2.1 = 3 x (1.8 x 2.1) true or false? Explain your reasoning
Answers
The expression is correct because changing the place in the multiplication operation does not affect the final result.
What is the equation?
An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that,the equation is 1.8 x 3) x 2.1 = 3 x (1.8 x 2.1) t
L.H.S
=(1.8×3)×2.1
=5.4×2.1
=11.34
R.H.S.
=3 x (1.8 x 2.1)
=3×3.78
=11.34
L.H.S.=R.H.S.
Thus, the expression is correct because changing the place in the multiplication operation does not affect the final result.

The speed of the boat is 0.125 miles/ minute, The time in which the total distance will be covered is 80 minutes.
What is Speed?
Speed is the rate at which an object travels certain distance in fixed period of time.
The distance covered by the boat is 10 miles
The time in which the distance is covered is 20 minutes
The speed of the boat is = distance / time
Speed = 2.5/ 20 = 0.125 miles/ minute
The time in which the total distance will be covered is
Time = 10 /0.125 = 80 minutes

2 as a fraction is 2/1.
Multiply: 3/2×2/1=6/2.
Simpliy: 6/2=3.
Therefore, the answer is 3.
1 times 2 is 2.
2+1 is 3.
We now put 3 over 2.
3 divided by 2 multiplied by 2 would cancel out the 2's so the resulting answer would be 3.
Or you can multiply them.

We know that different gardens can have different fractions of vegetables
in them. That right there tells us that we need some information about the
garden in order to know the fraction, because not all gardens are the same.
Since you haven't told us anything about Emma's garden, therefore, we have
no way to answer the question.
