If you mean a cross, such as the christ cross, quite simply one. However, if you mean a cross, similar to an x with equal length sides, the answer is two.

If you mean 5 and 7 then it is 10 and 14

Ratios can be written either like this 4/5 or 4:5 both mean 4 out of 5

to be identical or equal too

No. At best, it is approximately equal.

Two ratios, a:b and c:d are proportional if there is some number x such that a = cx and b = dx. Equivalently, if ad = bc (each is equal to cdx).

ratios that r the same

A proportion is an equation that states the two ratios are equal ie: a/b = c/d

Ratios that name the same comparisons

In a problem dealing with ratios, the cross produces are the product of the means, and the product of the extremes. These products are eauakl ro each other. Ratios can be written different ways. a:b :: c:d the means are the ones closest together (in the middle) their product is bc the extremes are ones fartherest apart (rt and left ends) their product is ad so .... bc = ad Ratios can also be written as fractions. a / b = c / d so bc = ad (same thing) Ex: if 3/x = 21/9 solve by using cross products 21x = 3(9) 21x = 27 x = 27 / 21 x = 1 and 2/7 or in decimal form 1.286 (rounded) There is also a cross product of vectors if you are studying them. If 2 vectors, a and b, are acting at some angle C to each other then their cross product is a x b = a b sin C , where a is the magnitude of vector a, similarly for b a x b is read as the cross product of vectors a and b, or just shortened to a cross b

The meaning is that the mass of reactants is equal to the mass of products.

No

It is a part of an expression related to ratios.
