To solve this problem, divide by the number of millimeters in an inch to get the fraction of an inch expressed as a decimal.

One inch is 2.54 centimeters, or 25.4 millimeters.

If you divide 1.5 by 25.4, the result is 0.059, or 59 thousandths of an inch.

You can divide both the top and bottom by 11 to reduce 11/22 to 1/2.

Percentages are fractions of 100, so 78% is the same 0.78 which as a fraction is 78/100.

You can reduce just like any other fraction, so 78/100 is the same as 39/50 (reduce using 2)

(4 x 2) - 2x + 3 = 0   ( group 4x2; order of operations)

8 - 2x + 3 = 0   ( solve 4 x 2 = 8)

11 - 2x = 0   ( combine 8 + 3 = 11 )

11 = 2x   ( add 2x … Read more

Exponent notation is a short-hand for multiplying a number by itself some number of times. For example, 10² is the same as 10 x 10. Here are a few more examples...

   5³ = 5 x 5 x 5 = 125

   2⁸ = 2 x 2 x 2 x 2 x 2 x 2 … Read more

Charged particles can be deflected by a magnetic field. Along with light, the sun generates are large volumes of charged particles, all of which are cast off in all directions in the form of solar radiation. When these charged particles head in the direction of the Earth, our planet's magnetic field deflects them so that … Read more

If two coins are tossed, there is a space of four possible results...

[ heads, heads]

[ heads, tails ]

[ tails, heads ]

[ tails, tails ]

...so there is a one in four (25%) chance of the result being both heads.

Similarly, there is a one in … Read more

Numbers in standard form are just the usual numeric notation, so your number is..

240.25

Your problem has the number expressed in what is called "written form" or "word form." Here's a link where you can find worksheets for converting numbers between standard and written form.

You can't do this with three lines, but you can do it with three folds. To get eight equal parts, you have to divide the circle into eight wedge shaped pieces. If you divide the circle in half with one bisecting line, you'll get two pieces. If you draw another line, you can cut those … Read more

A median is one value out of a range of numbers, so the idea of the median of a single number is something of a degenerate case. The median is a statistical value meaning the "number in the middle," so if you have a set of numbers it is the value numerically in the middle … Read more
