Which equation is an example of the associative property?
( 2 + 7 ) + 10 = ( 7 + 10 ) + 2 ( 3 * 9 ) * 4 = 3 * ( 9 * 4 ) The associative property means you can move the terms of the expression around without changing the value. Multiplication and addition are both associative.
What is the definition for the associative property?
The Associative Property is when you switch the parenthesis and your results should be the same results (if you didn't you did something wrong). The Associative Property only works for Addition and Multiplication ........NOT DIVISION OR SUBTRACTION!!! Ex: 7+(10+13) 7+23 30 (7+10)+13 17+13 30
Are prime numbers associative under multiplication?
(3 x 5) x 7 = 3 x (5 x 7) Of course, the product will no longer be prime.
What is the measure of the angle formed by a clock when it is 7?
When it is 7:00, the hour hand and minute hand of a 12-hour clock form a 150° angle.
What would 7 am be on a 24 hour time clock?
On a 24 hour clock, 7 am is 07:00 and is from midnight to noon. 7 pm is 19:00 and is from noon to midnight.
How can you use multiplication facts 1 and 2 to find 3 x 7?
The "multiplication facts" may be numbered differently in different textbooks, so it is really hard to guess what multiplication facts you are talking about. Better use the standard names, for example, "commutative property", "associative property", etc. For a multiplication such as 3 x 7, you either memorize the tables, your you do the repeated addition (3 x 7 = 7 + 7 + 7, that is, 7 appears 3 times as an addend.)
How can associative property of multiplication can help solve math problems mentally?
You can do the easy bits first. Thus, to calculate 7*5*2, instead of doing 35*2 = 70, you can calculate 7*10 = 70. By itself, the associative property is not as useful as it is in combination with the commutative and distributive properties.
What is 7.30am in 24 hour clock?
7:30 or 0730
What time is it if the time is the 19th hour?
The 19th hour is equivalent to 7:00 PM in the 24-hour clock format.
Why is 300 times 7 and 30 times 70 equal?
Its a miracle !! * * * * * That is one way of looking at it! Here's another: 300 * 7 = (30 * 10) * 7 which, by the associative property of multiplication, = 30 * (10 * 7) = 30 * 70 and there's the miracle!
How many times does the hour hand go round the clock in one week?
Every day the hour had travels once round the clock in the morning and one round the clock in the afternoon, so it travels twice round the clock in 1 day. There are 7 days in a week, thus the hour hand travels 7 x 2 = 14 times round the clock in a week.
What is 7 minutes to 7 in the evening in analog in 12 hour clock?
